The highlight and founding program of Singularity University, where I am chair of computing, is our summer program, now known as the Global Solutions Program. 80 students come from all over the world (only a tiny minority will be from the USA) to learn about the hottest rapidly changing technologies, and then join together with others to kickstart projects that have the potential to use those technologies to solve the world’s biggest problems.
This year is the 2nd year of a Google scholarship program, which means the program is free for those who are accepted. About 50 slots go to those scholarships, the other 30 go to winners of national competitions to attend. You can apply both ways. That means you can expect a class of great rising and already risen stars. I don’t like to exaggerate, but almost everybody who goes through it finds it life-changing.
If you are at a point where you are ready to do something new and big, and you want to understand how technology that keeps changing faster and faster works and how it can change the world and your world, look into it.
Also closing on Feb 19 is our accelerator program for existing or nascent startups. Applicants get $100K in seed funding, office space at Nasa Research Park and more through our network. You can read about it or Apply.
In a recent article, Car and Driver magazine compares 4 of the Highway autopilot systems, including those from Tesla, Mercedes, BMW and Infiniti. They test on a variety of roads, and spoilers: The Tesla wins by a good margin in several categories.
It’s a pretty interesting comparison, and a nicely detailed article. They drove a variety of roads, though the reality is that none of these autopilots are much use off the highway, and they are not intended to be as yet. Each system will perform differently on different roads. People report a much better score for the Tesla on Highway 280, which is the highway closest to Tesla HQ.
Still, it should wake up people who want to compare Google’s report of needing an intervention to prevent an accident every 70,000 miles (or 5300 miles between software anomalies) and needing intervention every 2 miles on the Tesla and twice a mile on the Infiniti, on average.

The California DMV hearings were contentious. You can hear a brief radio call-in debate with myself and one of the few people in favour of the regulations at KPCC’s “AirTalk”. Google threatened that if the regs are passed as written, they will plan to first deploy outside of California, and they probably mean it.

The Isle of Man is tiny but is its own country — they are giving serious consideration to being a robocar pilot location. Last year I had some talks with another channel island on the same topic. There are advantages to having your own country.
I recently read a report of a plan for a new type of intersection being developed in Malaysia, and I felt it had some interesting applications for robocars.
The idea behind the intersection is that you have a traditional intersection, but dig in one or both directions, a special underpass which is both shallow and narrow. One would typically imagine this underpass as being 2 vehicles wide in the center of the road but other options are possible. The underpass might be very shallow, perhaps just 4 to 5 feet high.
The underpass is available only to vehicles which fit, which is to say ordinary height passenger cars or even just ordinary height half-width vehicles. Big vehicles such as SUV, vans, trucks etc. would not use the underpass, and instead use the at-grade intersection, where you would have traffic signals or stop signs.
Why is this such a good idea? It’s vastly cheaper to make such an underpass. Because it’s so shallow, it is cheap to dig and shore up the walls. You can start the downramp much closer to the intersection because you don’t need to go so far down. It’s a tiny fraction of the cost of a regular overpass or underpass which requires lots of space to go up and down, and must be high enough for big trucks to pass underneath. Not so here, as trucks never go under it.
The downramp could begin a very short distance from the intersection, or it could begin further out to allow for a longer tunnel, such space now dedicated to the left turn lanes. (Or the right turn lanes if the tunnels are on the outside rather than center of the road.)
The center has the advantage of only digging one tunnel for both directions and providing that space for the left-turn lane. The downside is you have this physical tunnel entrance with protective bollards in the middle of a road, which may present some risk — though there are many places where there are tunnel entrances in the middle of roads, but they are full sized. Indeed we have intersections like this in full sized mode, including on Geary St. in San Francisco. The alternative on the edges requires two trenches and puts the obstacles to the side, mixing straight-through underpass traffic with right turning traffic.
Cars small enough to use the tunnels would get a transponder to signal their ability, possibly to raise a gate. In addition, a camera system would detect any too-large vehicle trying to enter the tunnel and do whatever it can to stop it. In the end, a too-large vehicle would end up hitting soft barriers if it failed to stop or divert. (Most parking lots today have hanging barriers to let vehicles know they won’t fit.)
Now the small, light vehicles, such as the one-person robocars, could bypass the traffic lights if they are red. They might get an “express” lane that is just for them which goes through these underpasses so it’s a smooth ride all along the road, other than the ups and downs.
Robocars would have a better time knowing where they fit and letting the intersection know they fit. More to the point, their ability to drive “on rails” would allow a wider robocar to go down a narrower tunnel, keeping a tiny margin that a human driver could never handle. Human driven vehicles would need to be narrower if they used these tunnels.
This would strongly encourage the use of small, lower-height vehicles, which are also very energy efficient. Really strongly — who would want to drive in a big SUV that has to stop at traffic lights when you can go nonstop in a small pod? Of course, you probably still use the light if making a turn. This in turn would cause a drop in vehicle size and congestion, and increase overall road capacity beyond what we get from having no stopping for a large fraction of vehicles.
If you want to get extreme, you could even have just a one lane tunnel if it’s all robocars. The simplest approach would be to have the express lane (with tunnels) only go in the commute direction during rush hour. Off peak, the robocars could pace their trips in pulses so that they alternate what direction they move through the underpass. On a north-south road, you could imagine during the red lights having 15 cars northbound, then 15 cars southbound back and forth until the light is green and you allocate the tunnel to the most popular direction. Humans could not obey this easily but robots could.
This works best when one of the roads intersecting is bigger than the other, since it’s harder to have both routes get an underpass. You could have one take a deeper underpass — at 10’ deep under a 5’ deep one, it’s still not nearly as deep as a full road underpass. Or with all robocars, you could have the robots alternate through the underground intersection at full speed under computer control. People have built computer modules of this “reservation” style intersection for many years, but they never could solve the problem that not every car in an intersection is a trustable robocar, and as such, you can never make an intersection like this. If all cars are robocars, an underground at-grade intersection could easily allow traffic to flow on both routes, in both directions, with proper timing. Since you would not see the other vehicles coming it might not even be as scary.
I think these underpasses would pay for themselves in the increase in road efficiency they would generate, but if not, you could also require a toll to use them. I think a lot of people would pay a modest toll to have no red lights on their trip. Since all you need do is dig a shallow trench, shore up the walls, and cover it with metal plates or similar, it’s a completely different scale of problem from a real underpass. Without too much money, every major road could become a non-stop robocar road.
You can, of course, create more capacity by building full elevated guideways only for use by small, light vehicles. These are again, much cheaper to build than full roads that can handle heavy trucks, and they take up only pillar space so they can be run down the center of many roads. They still need to be up high enough for big vehicles to go under them. Aside from the cost, the big issue is how they change the built environment, blocking out the sun and putting vehicles running in front of the 2nd or 3rd floor of buildings and houses. This is like a PRT plan but you only need to build these in the most congested zones.
I’m doing a lot of flying these days for international speaking and consulting, and I try whenever possible to have 2 or more clients when I fly overseas, since the trips and time-changes can be draining.
By far my favourite flight search tool is Google flight search. That’s because it’s an order of magnitude faster than most of the other tools, and while it lacks some features I would like, once you have speed, there is no substitute for it. I also like routehappy when I am being particular about seats, though it doesn’t cover all airlines which makes it useless for primary search.
To save money, however, what I really need is a tool that can get smart about the various arcane prices airlines put on flights which can vary tremendously. In particular the situations where airlines have decided not to simply sell one-way fares at around half the price of return trips. This is almost universally true between the USA and Europe and on some domestic routes, and less true on travel involving Asia. It is quite common for one-way trips to cost the same as round trips, and sometimes, bizarrely, even more. In the case of some KLM flights, I have found a one way costing double the price of a round trip. The Dutch know this and commonly book returns on KLM and don’t fly the return leg. There are stories of airlines punishing people who do that but they are rare. (The airlines are much more upset about “hidden city” booking, where people notice a flight to X connecting through Y is much cheaper than the direct flight to Y, so they book to X and just walk off the plane there.)
Throwing away the return leg doesn’t stop the trip from costing as much as a return. Your goal is to pay a more fair price, and that usually means making sure that you fly all your flights (or certainly your transatlantic flights) ticketed by the same airline. That works some of the time, but not always. The best airline to fly out may be a terrible airline to fly back on. You may have to take a flight with a painful time and routing one way to get the schedule you need the other way. Of course, this is the supposed purpose of the pricing — to make you buy both directions from the same airline, but it’s often a false victory, I suspect it loses for the airline almost as much as it wins, and it pisses off customers.
Trying all the permutations
Airlines have tons of hidden fare rules that jack up or seriously reduce fares involving certain cities. If you are going to these cities, you want to use them.
If we consider a complex trip that goes A -> B -> C -> D -> E -> A (4 stops) you can put that into most of the flight search engines as a “multi city” trip. You’ll sometimes get back a great answer, but usually you get back a ridiculous one. That’s because the engine just shops that out to all the airlines, which means you only get airlines that sell all 5 routes. And if the itinerary is far flung, there may be no airlines that sell them all at a good price, or with a good routing. (Of course, rarely does any one airline fly all the routes, but they all have tons of partners they can build tickets from.)
So it turns out the best way to fly this trip means combining one-ways (where they are fairly priced) and open jaws. I have found, for example, that you can often save a huge amount of money by buying something like “A->B, D-E” from one airline and “B->C, E-A” from another and “C->D” one way from a third. Bizarrely, adding the right extra legs to certain itineraries triggers serious price drops. This is particularly true when you involve cities with lots of competition (like New York) or inherently low prices (like India.)
So what I want is a flight search engine that will try all the combinations. There are engines that will check if sets of one-ways will do the trick (Kayak calls it a hacker fare) but that’s not enough. Price all 5 together, and then the sets of 4 with a single one-way, then the sets of 3 with the different sets of 2 and so on. You want to combine the price search with a flight quality search too, so that you flight on shorter, better flights.
When I do this as a human, I do it with some knowledge of the geography. For example, if you have a short leg which is only flown nonstop by one airline, it’s pretty obvious you want to price that out independently from the other flights, because if your ticket comes from an airline that doesn’t partner with the nonstop airline, they will put you on a ridiculous connection instead of a cheap one-hour flight.
In addition, there is another advantage to breaking up a flight into smaller groupings. It gives you more ability to change the flights or even to skip them. In many cases, to avoid people playing tricks, airlines will cancel the rest of an itinerary if you don’t show up for an early leg, often with no refund. Once, when a change in plans put me in Copenhagen instead of Bergen, Norway the night before my planned flight from Bergen back to San Francisco (via Copenhagen), SAS insisted I fly to Bergen just so I could turn around and get on the flight back to Copenhagen for my connection.
Round the world
This gets worse when you do a multi-leg trip, and worse, a “round the world” trip involving Asia, Europe and the Americas. In the latter case, sometimes your best course is the special around-the-world tickets offered by the 3 big alliances. These tickets cost around $10,000 in business class, around $4K in coach. For certain types of trips they are the clear winning choice. They are flexible — you can book them as little as 3 days in advance, and you can change your flights, even the cities, for free or low cost. They are refundable with a small penalty! You can add side trips for personal travel at little to no extra cost, and you can go to obscure airports that are expensive to fly to for the same price. They have a small number of downsides:
They can cost more than many directly booked trips. If your client is paying, it may not be fair to charge them $10K for something you could book for $7K. Though you can always eat the extra cost if you are doing side-trips as it can easily be worth it.
You are limited to one alliance only, though most of them have several airlines to fly you on the route.
They fetch from a more limited inventory if flying in business class, so quite often, particularly if booking late or changing your plans, you may see the flight you want is not available in the class you paid for.
Of course, they have their RTW restrictions — you must cross each ocean exactly once, along with a few others. Usually not a problem, but sometimes.
So if you ever see that your complex trip is adding up to a high cost, look into these. OneWorld also has some subset trips that don’t require a Pacific crossing.
Smart travel agents
While a computer should be able to do all this, perhaps there are still members of the dying profession of travel agents who can do a decent job on this. Let me know if you know of some. In the past, there were ticket consolidators, who buy up buckets of tickets and then have the power to sell them at reasonable one-way prices. This can be good, though sometimes it means being a 2nd class passenger, not getting loyalty miles and not being able to deal directly with the airline for service.
In 2010, I proposed the idea of planes with no landing gear which land on robotic platforms. The spring loaded platforms are pulled by cables and so can accelerate and turn with multiple gees, so that almost no matter what the plane does, it can’t miss the platform, and it can even hit hard with safety.
Today I learned there is a European research project called Gabriel with very similar ideas. In their plan, the plane has landing pillars which insert into the platform, rather than wheels. This requires retractable pillars but not the weight of the wheels. The platform runs on a maglev track but can tilt and rotate slightly to match the plane as it lands or takes off.
Overall I still prefer my plan — and I have added some refinements in the intervening years.
I am not quite sure of the value of maglev, which is quite expensive. Cables can provide high acceleration quite well.
The pillars still need a complex mechanism (which can fail) though they make a very solid connection — if you can place them just right.
Their platform tilts up — this may mean it can provide power longer which could be useful. It also allows easier release of pillars.
My approach allowed, in theory the ability to land in any direction, eliminating crosswinds. Gabriel uses a linear track.
I don’t think there is much need for communications between the aircraft and the platform. Can’t see much the platform can’t figure out — it can easily track the aircraft with its cameras and position itself. There are a few things that could be communicated, but why not have it work fine even if the communications are out — which could happen.
My goal was to have a super short runway, taking off and landing with high acceleration.
My aim was to handle small aircraft, Gabriel seems aimed at larger ones. Admittedly larger ones may be more tolerant of landing only at prepared airports.
One refinement I have added involves the hard question of what to do if you lose power at takeoff. This is the scariest thing in flying, and you must be able to recover. You could have a longer takeoff runway, so that there is enough space to slow down again if the aircraft loses power just before being released.
An alternative, as suggested by Gregg Maryniak is to have a “catch” airfield downrange from the main airfield. In this case, if you lost power, the system could keep accelerating you and even release you, with enough power that you can climb over the intervening space and then glide to a landing on an emergency catch platform — which would grab you no matter what, and let you land hard. The intervening land could be farmland or any sort of land use willing to be at the end of an airport, but it need not be airstrip. The downside of this is you must take off along a vector which lets you get, with no power, to the catch robot, so you may have to deal with crosswinds. You could have more than one catch robot allowing different takeoff vectors, but it’s still vastly less land than a typical airport would require, with most of the land finding other uses. Indeed it might be possible to have a small set of catch robots arrayed around the takeoff airstrip and allow takeoff in almost any direction.
The emergency catch robots, being only for emergencies, might stop you faster than an ordinary landing, and thus require less land. For example, if you can take 20m/s/s of deceleration (2gs) you can stop from 40m/s in just 40 meters, meaning the emergency catch strip could be very small, an insignificant amount of land. At such a small size, it’s easy to imagine an array of pads around the main takeoff-zone. Admittedly it’s a hard landing, but it would be a rare exception. Better be belted in on takeoff and everything stowed in the back.
It seems concluded for now, but it will be interested to see if anything develops further.
I’ve been electric car shopping, but one thing has stood out as a big concern. Many electric cars are depreciating fast, and it may get even faster. I think part of this is due to the fact that electric cars are a bit more like electronics devices than they are cars. Electric cars will see major innovation in the next few years, as well as a decline in their price/performance of their batteries. This spells doom for their value. It’s akin to cell phones — your 2 year old cell phone still functions perfectly, but you dispose of it for a new one because of the pace of innovation. Electric cars are not at that pace, but they are skirting the phenomenon.
When it comes to Robocar, I remind people that the computer will be the most important part of the car, not the engine or other features. And the computer and software are on the Moore’s Law curve, like your phone. The battery system is not like this, but digital features are becoming more and more important parts of every car.
The most obvious cause of the big depreciation is not related to the cars. There is a $7500 federal tax rebate on a new electric car, so the moment you drive it off the lot, its blue book value drops an additional $7500. In addition, different states offer credits from of up to $5,000, and unless you take the car out of state, that amount will also drop off the value. This is the primary culprit for the huge depreciation numbers, but there is more.
Perversely, people with higher incomes don’t get California’s $2,500 credit, so for them, buying used is a very wise idea, because somebody else got the credit, and it’s reflected in the price of the car. Of course, if you are rich enough, you may tolerate paying $2,500 more than everybody else for the new car. In fact, if not for the sales tax, it would be a good strategy to get somebody else to buy a car for you and get the credit, then buy it from them. Or take over a lease (getting to that…)
There are rumours that vendors might even be trying to subsidize against this depreciation to avoid a collapse in the price of their cars. After all, such low used car value discourages confidence in the car (and steals away buyers of new cars.) Rumours suggest Nissan has been known to offer incentives to get people to keep their lease-returns rather than take them back, and there are stories of even Teslas getting low prices at auction, though in the retail market they have actually done pretty well.
The Leaf is the most popular electric car, and only it and the Tesla are real market cars from big players. The other cars are all “compliance” cars, made by companies who must meet quotas of green vehicles. The 2015 Leaf has a cited range around 80 miles, and users report a real range on the highway closer to 60 miles. For me, that means a car that can’t take me to San Francisco and back. The Leaf would handle a large fraction of my trips around Silicon Valley, but not being able to go to SF is a major detriment in this town. So I decided not to get a 2015 Leaf.
Better cars keep getting pre-announced
That decision was magnified when Nissan announced the 2016 Leaf would be able to do 107 miles. Technically, that’s enough for the San Francisco trip, though in reality it’s just on the edge. Any charging would allow the trip, including a 5 minute (“gas pump” level) stop at a DC supercharger (if nobody else is using it.) So I was waiting for that car to come out when…
They announced the Chevy Bolt, a $30K car (after rebate) with a 200 mile range. Finally a reasonably priced car with enough range. And then rumours circulated of a similar range in the 2017 Leaf — it needs to if it will compete, and so every other car needs to as well. Who will buy a 100 mile 2016 car when a 200 mile 2017 car for not much more is being promoted?
Of course, in a year, something even more appealing than the Bolt will be announced. While the Bolt’s range is enough for 99% of my drives (leaving out only Lake Tahoe and road tripping) there is still much that can improve — other parts of the car, the electronics, and of course the battery pack getting even cheaper at that range.
Every year, cars get a little bit better, but we’re in for a period of about 5 years in electric cars where each new year is a lot better, and that’s trouble for people trying to sell them if the customers figure that out. A cell phone is cheap enough to throw out after 2 years. A car is not. To top it off, in a few years the robocar features will start getting more serious (starting with the first no-supervision traffic jam assist) and so other parts of the car will also be on the Moore’s Law curve.
The battery is probably not on that curve, but it’s on a good one. The Bolt’s 200 mile range is a result of an expected reduction of battery cost from $500/kwh a couple of years ago to $200/kwh by 2020, and that’s without any breakthroughs or new chemistry. (It is speculated the Bolt’s battery cost will already beat that $200 number.) Breakthroughs — which sometimes come when enough money is pushing the process — could easily do much more.
Robocars have an answer to this rapid depreciation. If they are used as Taxis, they can survive. The typical New York Taxi drives 62,000 miles each year and wears out in 5 years. Personal cars take 19 years to wear out, and go around 200,000 miles. Robotaxis will wear out and be scrapped after just 5 years, which means it is less of a burden when they are 4 years old and obsolete from a technology standpoint. (We may also design these vehicles to make it easy to give them hardware upgrades so their electronics can keep pace.)
Personal robocars have it harder. Your 4 year old personal vehicle is going to look like crap compared to the new ones. It will get software updates to match them (which is vital) but without hardware updates it will, like an old iPhone, no longer even be able to handle the software updates. If you buy a personal robocar, get one where it’s easy to swap out the hardware, and expect to pay the cost of this.
Wear and tear of electric cars
The battery is the lifeblood of the electric car. No matter how new the rest is, a reduced range is a deal-killer for most buyers. Indeed, some predictions say the rest of the power train should wear out more slowly than traditional cars, so the depreciation is unfair in some ways.
Battery swap is an option on some electric cars, but that’s a big cost to pay over what you planned to pay. Older battery packs will still work, but deliver less range. Owners will salivate for new packs that are cheaper, lighter, fresher and possibly even higher capacity than what they have. That’s all good, but if you buy an electric car with a pack only good for 4 years at today’s prices, you’ve lost all the economies the electric car hopes to give you. Of course, robocars and especially robotaxis can manage their batteries for much longer life
It might make sense to buy a 2012 Leaf for $8,000 and pay $5K to add a battery pack to it that’s brand-new, giving you a car close to matching a new one in certain ways.
With all this, why look at electric cars today? For me, my electricity bill would actually go down due to metering differences, and of course my gasoline bill would drop too. And they are zippy and fun to drive and quite green with California’s (relatively) green energy grid. And because of this depreciation, used ones are a major bargain. The buyers of new cars (and the federal government) took the hit on a new electric, but you can pick up a 2012 Leaf for $8,000. That’s because all those 2012 units are coming off their leases, and people want them a lot less with those fancier models out there. (In addition, it is known the 2012 had some battery life issues fixed in 2013.)
A lot of people are leasing electric cars. Leasing has one financial advantage (you pay sales tax only on the depreciation you take, rather than the whole car) and otherwise it’s a bad idea unless you’re sure the vendor has guessed badly on the residual value of the car after the lease. With electric cars, you take so much of the depreciation that the tax advantage is not so great. But many electric owners are leasing. The $2500 tax credit in California can often pay for the downpayment, making it easy to come up with the money, and owners are, with good reason, willing to let the vendor take the risk on battery decay and mega-depreciation. Vendors are not idiots, though, and so their residual values are low, but perhaps not low enough. Of course, if you know better cars are coming and are sure you only want the car for 2 years, leasing can ease your legwork.
On the other hand, you can sometimes take over the lease of another electric car owner, letting them suffer the “due at signing” downpayment (which often exceeds all the monthly payments on a short lease) and giving you a car for a very short time, which might be a wise choice with all the new vehicles coming down the pipe.
While I’ve been in love for a long time with the idea of mobility-on-demand and the robocar taxi, I continue to have some privacy concerns. The first is simply over the idea that a service company gets a map of all your travels. Of course, your cell phone company, and companies like Google with their Location History (Warning, don’t click or you will be freaked out if you didn’t know about this) know this already, as does the NSA and probably all the other spy agencies in the world. That doesn’t make it much better to add more trackers. The online ride companies like Uber are tracking you too.
It will be sad to lose the anonymous taxi we used to have, where you hailed a cab and paid in cash and no record was made (until cabs got tracklogs and video) of your travels. In my article on Robocars and Privacy written many years ago I outlined some plans for anonymous taxi service and I continue to push this idea.
In the article, I outline the concern that a taxi company will want to be able to photograph the vehicle when you’re not in it, to assure you haven’t dirtied or damaged the interior, and also to check if you left something in the vehicle by accident. People will be less comfortable with a camera that can be turned on all the time, and LEDs to inform you if a camera is on can’t really be trusted, so we want to have a physical shutter.
This led me to a simple solution: The physical shutter on the camera could be the switch by which you signal the start and end of a ride. The ride can’t begin until you close the physical shutter, and it doesn’t close out until you open it. You want a lever for the shutter on the outside of the car by the main passenger door, so you can open and close it when you are not in the car, so it doesn’t take a picture of you if you are trying to use an anonymous taxi. A connected lever inside could allow people who are not trying to be anonymous (but rather just private on their journey) to both control the shutter, and signal the car to go or conclude the ride.
You might not want to be inside when it takes the photo anyway, because a bright flash would be advised, for a millisecond brighter than the sunlight coming in the car. That way the images will be under the same light, night or day, making it easy to compare before and after images to detect dirt or lost items.
If you leave the car without opening the shutter, it would honk at you, or ding on your phone to remind you to come back and open it.
Cars will likely have some other cameras too, for video conferencing. I expect video conferences to be popular in robocars, and while your own phone can do that for you, a camera with stabilization in it could be a useful idea. Here, we could use a physical shutter, though this time with a remote actuator that makes noise, so you can easily see if it’s open. Even more simply, the video camera and monitor might not connect to anything in the car, but rather only connect to your phone via a car dock. (The connection must be wired, unfortunately.) If the camera is not connected you can be reasonably confident it’s not spying on you.
Of course, a truly malicious operator could have hidden cameras, or a secret connection to the video conference camera, but there’s not to much you can do about that. What we want protection from are attackers breaking into the car’s system, and vendors who change their mind about your privacy. We also want a stake in the ground that routine surveillance of passengers is not acceptable.
NHTSA, the federal car safety agency has been talking about getting into the robocar game for a while, and now declares it wants more involvement with two important details:
Unlike California, they are keen on making sure full robocars (able to run unmanned) are part of the regulations, and
Their regulations might supersede those of states like California.
In the next six months, the DoT will work with states and others on a unified policy. There are some other details here.
(California, by the way will have hearings in the next couple of weeks on their regulations. I will be out of the state, unfortunately.)
On top of this there is a $4 billion (over 10 years) proposal in the new Obama budget to support and accelerate robocars and (sadly) connected cars.
Perhaps most heartening is a plan to offer reduced regulation for up to 2,500 early deployment vehicles — a way to get companies out there in the field without shackling them first. Public attitudes on robocars have pushed regulators to a rather radical approach to regulation, namely attempting to define regulations before a product is actually on the market, with California even thinking of banning unmanned cars before they arrive. In the normal history of car safety regulation, technologies are built and deployed by vendors and are usually on the road for decades before they get regulated, but people are so afraid of robots that this normal approach may not happen here.
GM Delays super-cruise again
There was a fair bit of excitement when Cadillac announced “super-cruise,” a product similar to what you see in the Tesla autopilot, for the 2014 model year, or so we thought. It was the first effort from a big car company at some level of self-driving, even if minimal. Since then, they’ve kept delaying it, while Mercedes, Tesla and others have released such products. Now they have said it won’t show until at least 2017. GM is quickly dropping in the ranks of active Robocar companies, leaving the U.S. mantle to Tesla and Ford. Chrysler has never announced anything an even ran anti-self-driving-car ads in the Superbowl a few years ago.
Tesla releases “summon” and hints at more
The latest Tesla firmware release offers a “summon” function, so you can train your car to park and come back to you (with a range of 39 feet.) Primary use is to have your car go park itself in the garage, or at a robotic charging station. This didn’t stop Elon Musk from promising we are not very far away from being able to summon the car from very far away.
The pace of news is getting fast. Even I’m having trouble keeping up with everything even though it’s part of my job. This blog will continue to be a place not for all the news, but the news that actually makes a difference, with analysis.
Here are some other items you might find of interest:
A new news web site from Continental, one of the Tier 1 suppliers building self-driving systems. This is general news, not directly about Continental.
Ford is testing in snow up in Michigan. Localizing on snow is not hard with LIDAR if there are lots of poles, signs and other objects which stick up above the snow. Driving a freshly covered road with no landmarks will be harder. Another issue is deciding what to do when other cars have chosen to “make a lane” in the wrong place, when you know where the lanes really are.
Chris reports two interesting statistics. The first is “simulated contacts” — times when a safety driver intervened, and the vehicle would have hit something without the intervention:
There were 13 [Simulated Contact] incidents in the DMV reporting period (though 2 involved traffic cones and 3 were caused by another driver’s reckless behavior). What we find encouraging is that 8 of these incidents took place in ~53,000 miles in ~3 months of 2014, but only 5 of them took place in ~370,000 miles in 11 months of 2015.
(There were 69 safety disengages, of which 13 were determined to be likely to cause a “contact.”)
The second is detected system anomalies:
There were 272 instances in which the software detected an anomaly somewhere in the system that could have had possible safety implications; in these cases it immediately handed control of the vehicle to our test driver. We’ve recently been driving ~5300 autonomous miles between these events, which is a nearly 7-fold improvement since the start of the reporting period, when we logged only ~785 autonomous miles between them. We’re pleased.
Let’s look at these and why they are different and how they compare to humans.
The “simulated contacts” are events which would have been accidents in an unsupervised or unmanned vehicle, which is serious. Google is now having one once every 74,000 miles, though Urmson suggests this rate may not keep going down as they test the vehicle in new and more challenging environments. It’s also noted that a few were not the fault of the system. Indeed, for the full set of 69 safety disengagements, the rate of those is actually going up, with 29 of them in the last 5 months reported.
How does that number compare with humans? Well, regular people in the USA have about 6 million accidents per year reported to the police, which means about once every 500,000 miles. But for some time, insurance companies have said the number is twice that, or once every 250,000 miles. Google’s own new research suggests even more accidents are taking place that go entirely unreported by anybody. For example, how often have you struck a curb, or even had a minor touch in a parking lot that nobody else knew about? Many people would admit to that, and altogether there are suggestions the human number for a “contact” could be as bad as one per 100,000 miles.
Which would put the Google cars at close to that level, though this is from driving in simple environments with no snow and easy California driving situations. In other words, there is still some distance to go, but at least one possible goal seems in striking distance. Google even reports going 230,000 miles from April to November of last year without a simulated contact, a (cherry-picked) stretch that nonetheless matches human levels.
For the past while, when people have asked me, “What is the biggest obstacle to robocar deployment, is it technology or regulation?” I have given an unexpected answer — that it’s testing. I’ve said we have to figure out just how to test these vehicles so we can know when a safety goal has been met. We also have to figure out what the safety goal is.
Various suggestions have come out for the goal: Having a safety record to match humans. Matching good humans. Getting twice or even 10 times or even 100 times as good as humans. Those higher, stretch goals will become good targets one day, but for now the first question is how to get to the level of humans.
One problem is that the way humans have accidents is quite different from how robots probably will. Human accidents sometimes have a single cause (such as falling asleep at the wheel) but many arise because 2 or more things went wrong. Almost everybody I talk to will agree a time has come when they were looking away from the road to adjust the radio or even play with their phone, and they looked up to see traffic slowing ahead of them, and quickly hit the brakes just in time, narrowly avoiding an accident. Accidents often happen when luck like this runs out. Robotic accidents will probably mostly come from one single flaw or error. Robots doing anything unsafe, even for a moment, will be cause for alarm and the source of the error will be fixed as quickly as possible.
This leads us to look at the other number — the safety anomalies. At first, this sounds more frightening. They range from 39 hardware issues and anomalies to 80 “software discrepancies” which may include rarer full-on “blue screen” style crashes (if the cars ran Windows, which they don’t). People often wonder how we can trust robocars when they know computers can be so unreliable. (The most common detected fault is a perception discrepancy, with 119. It is not said, but I will presume these will include strange sensor data or serious disagreement between different sensors.)
It’s important to note the hidden message. These “safety anomaly” interventions did not generally cause simulated contacts. With human beings, the fact that you zone out, take your eyes off the road, text or even in many cases even briefly fall asleep does not always result in a crash for humans, and nor will similar events for robocars. In the event of a detected anomaly, one presumes that independent (less capable) backup systems will immediately take over. Because they are less capable, they might cause an error, but that should be quite rare.
As such, the 5300 miles between anomalies, while clearly in need of improvement, may also not be a bad number. Certainly many humans have such an “anomaly” that often (that’s about every 6 months of human driving.) It depends how often such anomalies might lead to a crash, and what severity of crash it would be.
The report does not describe something more frightening — a problem with the system that it does not detect. This is the sort of issue that could lead to a dangerous “careen into oncoming traffic” style event in the worst case scenario. The “unexpected motion” anomalies may be of this class. (As such would be a contact incident, we can conclude it’s very rare if it happens at all in the modern car.) (While I worked on Google’s car a few years ago, I have no inside data on the performance of the current generations of cars.)
I have particular concern with the new wave of projects hoping to drive with trained machine learning and neural networks. Unlike Google’s car and most others, the programmers of those vehicles have only a limited idea how the neural networks are operating. It’s harder to tell if they’re having an “anomaly,” though the usual things like hardware errors, processor faults and memory overflows are of course just as visible.
The other vendors
Google didn’t publish total disengagements, judging most of them to be inconsequential. Safety drivers are regularly disengaging for lots of reasons:
Taking a break, swapping drivers or returning to base
Moving to a road the car doesn’t handle or isn’t being tested on
Any suspicion of a risky situation
The latter is the most interesting. Drivers are told to take the wheel if anything dangerous is happening on the road, not just with the vehicle. This is the right approach — you don’t want to use the public as test subjects, you don’t want to say, “let’s leave the car auto-driving and see what it does with that crazy driver trying to hassle the car or that group of schoolchildren jaywalking.” Instead the approach is to play out the scenario in simulator and see if the car did the right thing.
Delphi reports 405 disengagements in 16,600 miles — but their breakdown suggests only a few were system problems. Delphi is testing on highway where disengagement rates are expected to be much lower.
Nissan reports 106 disengagements in 1485 miles, most in their early stages. For Oct-Nov their rate was 36 for 866 miles. They seem to be reporting the more serious ones, like Google.
Tesla reports zero disengagements, presumably because they would define what their vehicle does as not a truly autonomous mode.
VW’s report is a bit harder to read, but it suggests 5500 total miles and 85 disengagements.
If the number is the 100,000 mile or 250,000 mile number we estimate for humans, that’s still pretty hard to test. You can’t just take every new software build and drive it for a million miles (about 25,000 hours) to see if it has fewer than 4 or even 10 accidents. You can and will test the car over billions of miles in simulator, encountering every strange situation ever seen or imagined. Before the car has a first accident it will be unlike a human. It will probably perform flawlessly. if it doesn’t, that will be immediate cause for alarm back at HQ, and correction of the problem.
Makers of robocars will need to convince themselves, their lawyers and safety officers, their boards, the public and eventually even the government that they have met some reasonable safety goal.
Over time we will hopefully see even more detailed numbers on this. That is how we’ll answer this question.
This does turn out to be one advantage of the supervised autopilots, such as what Tesla has released. Because it can count on all the Tesla owners to be the fail-safe (or if you prefer, guinea-pig) for their autopilot system, Tesla is able to quickly gather a lot of data about the safety record of its system over a lot of miles. Far more than can be gathered if you have to run the testing operation with paid drivers or even your own unmanned cars. This ability to test could help the supervised autopilots get to good confidence numbers faster than expected. Indeed, though I have often written that I don’t feel there is a good evolutionary path from supervised robocars to unmanned ones, this approach could make my prediction be in error. For if Tesla or some other car maker with lots of cars on the road is able to make an autopilot, and then observe that it never fails in several million miles, then they might have a legitimate claim on having something safe enough to run unmanned, at least on the classes of roads and situations which the customers tested it on. Though a car that does 10 million perfect highway miles is still not ready to bring itself to you door to door on urban streets, as Elon Musk claimed would happen soon with the Tesla yesterday.
Ford’s CEO talks like he gets it. Ford did not have too much to show — they announced they will be moving to Velodyne’s new lower cost 32-laser puck-sized LIDAR for their research, and boosting their research fleet to 30 vehicles. They plan for full-auto operation in limited regions fairly soon.
Ford is also making its own efforts into one-way car share (similar to Daimler Car2Go and BMW DriveNow) called GoDrive, which pushes Ford more firmly into the idea of selling rides rather than cars. The car companies are clearly believing this sooner than I expected, and the reason is very clearly the success of Uber. (As I have said, it’s a mistake to think of Uber as competition for the taxi companies. Uber is competition for the car companies.)
Ford is also doing an interesting “car swap” product. While details are scant, it seems what the service will do is let you swap your Ford for somebody else’s different Ford. For example, if somebody has an F-150 or Transit Van that they know they won’t use the cargo features on some day or weekend, you drive over with your ordinary sedan and swap temporarily for their truck — presumably with a small amount of money flowing to the more popular vehicle. Useful idea.
The big announcement that didn’t happen was the much-rumoured alliance between Ford and Google. Ford did not overtly refute it but suggested they had enough partners at present. The alliance would be a good idea, but either the rumours were wrong, or they are waiting for another event (such as the upcoming Detroit Auto Show) to talk about it.
Faraday Future, where art thou?
The big disappointment of the event was the silly concept racecar shown by Faraday Future. Oh, sure, it’s a cool electric racecar, but it has absolutely nothing to do with everything we’ve heard about this company, namely that they are building a consumer electric car-on-demand service with autonomous delivery. Everybody wondered if they had booked the space and did not have their real demo ready on time. It stays secret for a while, it seems. Recent hires, such as Jan Becker, the former head of the autonomous lab for Bosch, suggest they are definitely going autonomous.
Mapping heats up
Google’s car drives by having super-detailed maps of all the roads, and that’s the correct approach. Google is unlikely to hand out its maps, so both Here/Navteq (now owned by a consortium of auto companies in Germany) and TomTom have efforts to produce similar maps to licence to non-Google robocar teams. They are taking fairly different approaches, which will be the subject of a future article.
One interesting edge is that these companies plan to partner with big automakers and not just give them map data but expect data in return. That means that each company will have a giant fleet of cars constantly scanning the road, and immediately reporting any differences between the map and the territory. With proper scale, they should get reports on changes to the road literally within minutes of them happening. The first car to encounter a change will still need to be able to handle it, possibly by pulling over and/or asking the human passenger to help, but this will be a very rare event.
MobilEye has announced a similar plan, and they are already the camera in a large fraction of advanced cars on the road today. MobilEye has a primary focus on vision, rather than Lidar, but will have lots of sources of data. Tesla has also been uploading data from their cars, though it does not (as far as I know) make as extensive use of detailed maps, though it does rely on general maps. read more »
Lyft announced a $500M investment from GM with $500M more, pushing them to a $5.4B valuation, which is both huge and just a tenth of Uber. This was combined with talk of a push to robocars. (GM will provide a car rental service to Lyft drivers to start, but the speculation is that whatever robocar GM gets involved in will show up at Lyft.)
With no details, Lyft’s announcement doesn’t really add anything to the robocar world that Uber doesn’t already add. It is GM’s participation that is more interesting, because it’s another car company showing they are not just giving lip service to the idea of selling rides rather than cars. (Mercedes and BWM have also started saying real things in this area.)
My initial expectations for the big car companies were much more bleak for them. I felt that their century long histories of doing nothing but selling cars would impede them from switching models until it was too late. That might still happen, and will happen for some companies, but more might survive than expected. The story also contains some more pure PR comments about OnStar in the new Lyft rental cars. Lyft drivers are all linked in real time with their smartphones; OnStar is obsolete technology, named only to make it seem GM is adding something. GM is not a great robocar leader. They have been very slow even with their highway “super cruise” efforts and the best they have done is partner with Rajkumar at CMU only to find Uber more successful at working with CMU folks.
Sidecar and where are you going?
Also frightening is the news last week of the death of Sidecar. Sidecar was the 3rd place smartphone-hail company after Uber and Lyft, but so distant a third that it decided to shut down. Where Lyft can raise another billion, Sidecar could not get a dime. The CEO is a friend of mine and I’ve been impressed that Sidecar was willing to innovate, even building a successful delivery business on top of the fact that you had to tell Sidecar where you were going. I think it’s important that users say where they are going. It allows much better planning of the use of robocar resources. If customers say where they are going, you can not only do some of the things Sidecar did (deliveries in the trunk the passenger doesn’t even know about, pricing set by drivers, directional goals set by drivers etc.) you can do more:
Send short-range cars (electric cars) for short trips
Send small (one or two person) cars when there is just one rider
Send cars not even capable of the highway if the trip doesn’t involve the highway
Pool riders far more efficiently, sometimes in vehicles designed for pooling which have 2-12 private “cabins.”
All of this is important to making transportation vastly more efficient, and in allowing a wide variety of vehicle designs, and a wide variety of power trains. It is only by knowing the destination that many of these benefits can be seen.
Uber lets you enter the destination but does not require it, and people do like having less to do when summoning a vehicle. (I always enter the destination when in places they don’t speak English, it’s a handy way to communicate with the driver.) The driver is not shown the destination until after they pick you up. This stops drivers from refusing rides going places they don’t want to go, which has its merits. It also has serious downsides for drivers, who sometimes at the end of their shift pick up a rider who wants to go 40 miles in the opposite direction of their home.
Even more frightening is what Sidecar’s death says about how much room there is for competitors in the robotaxi space. There are dozens of car makers competing for a new car customer, but San Francisco, the birthplace of Uber, Lyft and Sidecar, could not support 3 players in one of the world’s hottest investment spaces. Two unicorns, but nobody else.
When it comes to competition, the ride business is a strange one. For scheduled rides (which was most of the black car business before Uber) there are minimal economies of scale. A one-car limo “fleet” is still a viable business today, picking up customers for scheduled rides. They provide the same service as a 100 car limo-fleet, though they sometimes have to turn you down or redirect you to a partner.
For on-demand rides, there is a big economy of scale. I want a car now, so you have to have a lot of cars to be sure to have one near me. I will go with the service that can get to me soonest. While price and vehicle quality matter, they can be trumped by pickup time, within reason. Sidecar, being small, often failed in this area, including my attempt to use it on its last day on my way home from the airport.
Robocars offer up a middle ground. Because there is no driver who minds waiting, it will be common to summon a robocar longer in advance of when you want it. Once you know that “I’m leaving in around 20 minutes” you can summon, and the car can find somewhere to wait except in the most congested zones. Waiting time for a robotaxi can be very cheap, well under a dollar/hour, though during peak times, robotaxi owners will raise the price a little to avoid lost opportunity costs. (Finance costs will be under 20 cents/hour at 5% interest, and waiting space will range from free to probably 30 cents/hour in a competitive parking “spot market.”)
The more willing customers are to summon in advance, the more competitive a small player can be. They can offer you instant service when you actually are ready to leave, and that way they can compete on factors other than wait time. Small players can be your first choice, and they can subcontract your business to another company who has a car close by when you forget to summon in advance.)
CES in Las Vegas
I’m off to CES Wednesday. This show, as before promises to have quite a lot of car announcements. Rumours suggest the potential Ford/Google announcement could happen there, along with updates from most major companies. There will also be too many “connected” car announcements because companies need to announce something, and it’s easy to come up with something in that space that sounds cool without the actual need that it be useful.
This morning already sees an announcement from Volvo and Ericsson about streaming video in cars. This is a strange one, a mix of something real — as cars become more like living rooms and offices they are going to want more and better bandwidth, including bandwidth reliable enough for video conferencing — but also something silly, in that watching movies and TV shows is, with a bit of buffering, a high-bandwidth application that’s easy to get right on an unreliable network. Though in truth, because wireless bandwidth on the highway is always going to be more expensive than wifi in the parking space, it really makes more sense to pre-load your likely video choices to win both ways on cost and quality. I have been fascinated watching the shift between semi-planned watching (DVD rental, Netflix DVD queue, DVR, prepaid series subscriptions, watchlists and old-school live TV) and totally ad-hoc streaming on demand. While I understand the attraction of ad-hoc streaming (even for what you planned far ahead to watch) it surprises me that people do it even at the expense of cost and quality. Of course, there are parallels to how we might summon cars!
Yahoo Autos is reporting rumours that Google and Ford will announce a partnership at CES. Google has always said it doesn’t want to build the cars, and Ford makes sense as a partner — big, but with only modest R&D efforts of its own, and frankly a brand that needs a jolt of excitement. That means it will be willing to work with Google as a partner which calls many of the shots, rather than just viewing them as a supplier, which gets to call few of them. Ford has the car-making skills, global presence and scale to take this to any level desired. Besides, if Google really wanted, it could buy Ford with cash it has on hand. :-)
This is combined with the announcement of what I predicted earlier in the year — that Alphabet will spin out the self-driving car project (known internally as “Chauffeur”) into its own corporate subsidiary.
While the big story of the week was the California regulations here are some other items worth of note, and non-note.
No, a whiz-kid hasn’t duplicated what the big labs did
There was a fair bit of press about the self-driving car efforts of George Hotz. Hotz modified an Acura ILX to do some basic self-driving. It’s a worthwhile project, and impressive for a solo operator, but because of the amount of press hype was so large, Tesla even issued a “correction” which is pretty close to spot-on.
I don’t know Hotz or anything about his effort not in the story, but what is described is what were viewed as “solved problems” years ago by the major teams. What’s interesting about his effort is how much less work is required to do it today. The sensors are much cheaper, the computing is cheaper and smaller, the AI tools and other software tools are much better and more readily available, and the cars are easier to interface to.
In particular, Hotz gets to take advantage of two things not easy for early teams. Today’s cars are all controlled by digital signals on internal controller area network buses. Many cars are very close to “drive by wire” if you can use that bus. The problem is, most car vendors are very protective about their bus protocols, and also want to change them, so it’s hard to make a production system based on unsupported protocols learned via reverse engineering. Better to take the hard but certain route of pretending to be the sensors in the brake pedal and gas pedal, and wire on to the steering motor.
The other rising trend of interest is the surge of capability in convolutional neural networks and the “deep learning” algorithm. Google loves these tools and just open sourced the TensorFlow package to spread it out into the world. This is starting to affect the conclusions I wrote in my article several years ago on the question of whether cameras or lidar will be the primary sensor in a robocar. In that essay, I conclude that computer vision is still too uncertain a quantity to predict, while cheap lidar is a safe and easy prediction. Computer vision is improving faster than expected, though it’s still not there yet. It is this, I think, that gives Elon Musk the (still probably false) confidence to declare lidar as the wrong direction.
Many people with whom I have had conversations have felt that Tesla’s early autopilot release was reckless. And Elon Musk perhaps agrees, because he has noted that videos show customers clearly doing unsafe things with the autopilot. The Tesla autopilot handles most highway conditions, and in fact lulls people into thinking it handles them all. In reality it is a system that needs constant monitoring, like a good cruise control. Some of us have feared it’s a matter if when, not if, a Tesla on autopilot will have an incident.
One comment from Tesla has particularly concerned me. It is said the Teslas are improving every week based on learning from data gathered from all the Teslas out running in autopilot, perhaps a million miles a day. That is an impressive and useful resource, and Tesla has even said they would love for them to learn every day. Learning is good, but that rate of learning strongly suggests that no human quality assurance is being done on the results of the learning — the QA is being done by the customers. I fear that is not a safe approach at this stage of the technology.
Many more teams and entrants
Baidu has stepped up their efforts and now also will work on buses. They have also stepped up their partnership with BMW. Samsung has entered the fray as well as Kia (Hyundai announced big plans earlier this year.) Tata group has also announced plans but through the Tata Elxsi design division, not Tata Motors. (Mahindra earlier offered a prize for robocar development in India.)
The testing regulations did not bother too many, though I am upset that they effectively forbid the testing of delivery robots like the ones we are making at Starship because the test vehicles must have a human safety driver with a physical steering system. Requiring that driver makes sense for passenger cars but is impossible for a robot the size of breadbox.
Needing a driver
The draft operating rules effectively forbid Google’s current plan, making it illegal to operate a vehicle without a licenced and specially certified driver on board and ready to take control. Google’s research led them to feel that having a transition between human driver and software is dangerous, and that the right choice is a vehicle with no controls for humans. Most car companies, on the other hand, are attempting to build “co-pilot” or “autopilot” systems in which the human still plays a fundamental role.
The state proposes banning Google style vehicles for now, and drafting regulations on them in the future. Unfortunately, once something is banned, it is remarkably difficult to un-ban it. That’s because nobody wants to be the regulator or politician who un-bans something that later causes harm that can be blamed on them. And these vehicles will cause harm, just less harm than the people currently driving are doing.
The law forbids unmanned operation, and requires the driver/operator to be “monitoring the safe operation of the vehicle at all times and be capable of taking over immediate control.” This sounds like it certainly forbids sleeping, and might even forbid engrossing activities like reading, working or watching movies.
Drivers must not just have a licence, they must have a certificate showing they are trained in operation of a robocar. On the surface, that sounds reasonable, especially since the hand-off has dangers which training could reduce. But in practice, it could mean a number of unintended things:
Rental or even borrowing of such vehicles becomes impossible without a lot of preparation and some paperwork by the person trying it out.
Out of state renters may face a particular problem as they can’t have California licences. (Interstate law may, bizarrely, let them get by without the certificate while Californians would be subject to this rule.)
Car sharing or delivered car services (like my “whistlecar” concept or Mercedes Car2Come) become difficult unless sharers get the certificate.
The operator is responsible for all traffic violations, even though several companies have said they will take responsibility. They can take financial responsibility, but can’t help you with points on your licence or criminal liability, rare as that is. People will be reluctant to assume that responsibility for things that are the fault of the software in the car they use, as they have little ability to judge that software.
With no robotaxis or unmanned operation, a large fraction of the public benefits of robocars are blocked. All that’s left is the safety benefit for car owners. This is not a minor thing, but it’s a small a part of the whole game (and active safety systems can attain a fair chunk of it in non-robocars.)
The state says it will write regulations for proper robocars, able to run unmanned. But it doesn’t say when those will arrive, and unfortunately, any promises about that will be dubious and non-binding. The state was very late with these regulations — which is actually perfectly understandable, since not even vendors know the final form of the technology, and it may well be late again. Unfortunately, there are political incentives for delay, perhaps indeterminate delay.
This means vendors will be uncertain. They may know that someday they can operate in California, but they can’t plan for it. With other states and countries around the world chomping at the bit to get vendors to move their operations, it will be difficult for companies to choose California, even though today most of them have.
People already in California will continue their R&D in California, because it’s expensive to move such things, and Silicon Valley retains its attractions as the high-tech capital of the world. But they will start making plans for first operation outside California, in places that have an assured timetable.
It will be less likely that somebody would move operations to California because of the uncertainty. Why start a project here — which in spite of its advantages is also the most expensive place to operate — without knowing when you can deploy here. And people want to deploy close to home if they have the option.
It might be that the car companies, whose prime focus is on co-pilot or autopilot systems today, may not be bothered by this uncertainty. In fact, it’s good for their simpler early goals because it slows the competition down. But most of them have also announced plans for real self-driving robocars where you can act just like a passenger. Their teams all want to build them. They might enjoy a breather, but in the end, they don’t want these regulations either.
And yes, it means that delivery robots won’t be able to go on the roads, and must stick to the sidewalks. That’s the primary plan at Starship today, but not the forever plan.
California should, after receiving comment, alter these regulations. They should allow unmanned vehicles which meet appropriate functional safety goals to operate, and they should have a real calendar date when this is going to happen. If they don’t, they won’t be helping to protect Californians. They will take California from being the envy of the world as the place that has attracted robocar development from all around the planet to just another contender. And that won’t just cost jobs, it will delay the deployment in California of a technology that will save the lives of Californians.
I don’t want to pretend that deploying full robocars is without risk. Quite the reverse, people will be hurt. But people are already being hurt, and the strategy of taking no risk is the wrong one.
This summer, I started wondering what you might do to build a small farming robot to manage a home garden. I then discovered the interesting Farmbot project, which has been working on this for much longer, and has done much of what I thought might be useful. So I offer kudos to them, but thought it might be worth discussing some of the reasons why this is interesting, and a few new ideas.
The rough idea is to use robotics to manage a modest garden. It could be outside or in a greenhouse, or perhaps eventually a vertical farm on a wall. The simplest way to do this is to have a track and a gantry to allow the robot head to move to any spot in the rectangle and then do gardening tasks — tilling, planting seeds, watering, weed killing, weeding, analysis and even perhaps harvesting.
Why do people have gardens? Some do it because they enjoy the task, or at least some portions of the task. Those folks may not be interested in a farming robot, though they might like one which does the tiresome tasks like weeding.
Others garden to save money on produce, particularly specialty produce which is organic and where they know all about how it was grown. Initially, the robot might be too expensive to allow you to save money unless you pretend to ignore the cost of the robot.
Perhaps most interesting is the ability to get a supply of superior produce that’s already delivered to your house. The produce can be quite superior to agribusiness produce found in grocery stores, because many of those plants have been bred for things like shelf life, how well they pack and transport, how good they look on the shelf, yield, ripeness out of season and many other factors. The problem is, every time you breed for one of these, you breed out other things, including the most important — flavour. People with no love of gardening as a hobby will still pay well for food that tastes better.
To meet that last (and richest) market, you want a design that requires as little owner effort as possible. The owner would lay down the robot and pour in some soil, but ideally do very little else other than insert modules and possibly harvest.
The Farmbot today has a seed planting tool and a watering tool. Let’s look at other functions a farm robot might have:
Because the robot knows very precisely where it put each seed, anything not in those locations is a weed. Knowing this offers various weeding strategies, including the ability to tackle each weed within hours after it sprouts. There could be very precision application of weed killers, and they could be placed with such precision they might be stronger than usual. Mechanical weed destruction and removal is also possible. The system would also know when it failed, and has to summon a human. Bosch makes a weed killing robot for larger farms.
Simple hyperspectral cameras might eventually lead to super understanding of how plants are doing, and near-perfect estimation of ripeness, as well as amounts of feed and water to apply, again with full precision.
Insect pests could be spotted immediately, and some of them dealt with. It is not even out of the question they could be burned with lasers, which of course is super cool.
Animal pests (stealing the food) could be detected and harassed with motion, lights, sound or even that bug-killing laser. The robot could be a very superb scarecrow. Of course, netting could also be used on the garden since the human rarely has to access it.
The soil could be tilled by the robot. Analysis of the soil may make more sense to do remotely but it could be a service.
The system could tell you exactly when to pick every plant for perfection, or what the best plant to pick is when you want something. It might even be able to harvest certain plants with the right attachment and put them in a basket for you to collect.
The robot could anticipate frosts, requesting the humans to put a cover over the garden and even applying heat.
For the non-gardening gardener, you would just order cartridges online with seeds, nutrients or weed killer, plug them in and let it run. Then eat whatever is at the peak of flavour. The app could also arrange trading with neighbours — everybody likes being generous to neighbours with home produce. (Farmbot is open source but of course could make money from this business quite well.)
Over time, mass manufacturing might make this cheaper and more flexible. For example, eventually a free-roaming design could be possible that is of course much easier to install and could handle much larger plots of land. (It would need to go back to base to refill on water and electricity.) Knowing the garden so well (because it planted it) it could know where to put its wheels. It doesn’t matter how slow it is, so long as it’s quiet.
Vertical farming might be interesting. With a vertical farm on the wall, the robot might simply hang in front of the wall without even needing tracks, though it could not apply much force in that case.
Robots might even make practical something that started off silly — indoor farming with LED light sources. The idea of taking even solar panel energy and using it to shine lights indoors is silly compared to having a garden outdoors or having skylights, but people have slowly been making that more reasonable, using purple LEDs (no light wasted on the green plants don’t want) of high efficiency. Robots might be able to do even better, shining or concentrating light precisely on the leaves of plants so that little energy is spent lighting anything else. I have not done the math, but if anything can make this work, such precision might do the job.
Another road trip has meant fewer posts — this trip included being in Paris on the night of Nov 13 but fortunately taking a train out a couple of hours before the shooting began, and I am now in South Africa on the way to Budapest — but a few recent items merit some comment.
Almost every newspaper in the world reported the story of how a motorcycle cop pulled over one of Google’s 3rd generation test cars, the 2 seaters, and a lot of incorrect reports that the car was given a ticket for going too slow. Or that there was “no driver to ticket.” Today, Google’s cars always have a safety driver (who has a steering wheel) and who is responsible for the car in case it does something unexpected or enters an especially risky situation. So had there been a ticket to write, there would have been a driver in the car, just as there is if you get a ticket for speeding while using your cruise control.
Google’s prototype is what is known as a “Neighbourhood Electric Vehicle” or NEV. There are special NEV rules in place that make such vehicles much less subject to the complex web of regulations required for a general purpose vehicle. They need to be electric, must not travel on roads with a speed limit over 35mph and they must themselves not be capable of going more than 25mph. The Google car was doing 24mph when the officer asked the safety driver to pull over, so there was nothing to ticket. Of course, that does not mean an officer can’t get confused and need an explanation of the law — even they don’t know all of them.
The NEV regulations are great for testing, though there is indeed an issue around how the earliest robocars will probably want to go a little slow, because safety really is the top priority on all teams I know. As such, they may go as slowly as the law allows, and they may indeed annoy other drivers when doing that. This should be a temporary phase but could create problems while cars learn to go faster. I have suggested in the past that cars wanting to go slow might actually notice anybody coming up behind them and pull off the road, pausing briefly in driveways or other open spots, so that the drivers coming up behind never have to even brake. A well behaved unmanned vehicle might go slowly but not present a burden to hurried humans.
Ford may also avoid standby supervision
Recent reports suggest that Ford, like Google, may have concluded that there is not an evolutionary path from ADAS to full self driving, in particular, the so-called “level 3” which I call standby supervision, where a human driver can be called on with about 10 seconds notice (but not anything shorter) to resolve live driving problems or to take the wheel when the car enters a zone it can’t drive. This transition may just be too dangerous, Google has said, along with many others.
Cheaper LIDAR etc.
Noted without much comment — Quanergy, on whose advisory board I sit, as announced progress on the plans for an inexpensive solid state LIDAR, and plans to ship the first on schedule, in 2016. This sub-$1000 LIDAR keeps us on a path to even cheaper LIDAR, which should eliminate all the people who keep saying they want to build robocars without LIDAR — I am looking at you, Elon Musk. Nobody will make their first full robocar less safe just to save a few hundred dollars.
Also related to Starship, another company I advise, is the arrival of not one but two somewhat similar startups to build small delivery robots. “Dispatch Network” involves U.S. roboticists who participated in a Chinese based hardware accelerator and have a basic prototype, larger than the Starship robot. “Sidewalk” — a Lithuanian company, also has a prototype model and a deal with DHL to do research together with them on last mile robots.
I’m pleased to announce today the unveiling of a new self-driving vehicle company with which I am involved,
not building self-driving cars, but instead small delivery robots which are going to change the face of
retailing and last-mile delivery and logistics.
Starship Technologies comes out of Europe, created by two of the founders of Skype, Janus Friis and Ahti Heinla who
is CEO. The mission is similar to the vision I laid out in 2007 for the Deliverbot —
the self-driving box that can get you anything in 30 minutes for under a dollar.
Starship is still in early stages, but will be conducting a pilot project next year in the UK, and another in the
USA shortly thereafter. Customers will be able to place online orders and have a robot come to their home immediately
or on their schedule.
Why is this possible well before full unmanned self-driving cars can go into public use? There are all sorts of
The boxes are not in a super hurry:
They will go slowly and cautiously
They don’t mind detours, and can take the safest rather than shortest route to you
It’s not a big deal if they have to pause if they encounter children or anything confusing or risky, or need to wait for a remote operator to solve a problem
They will travel on the sidewalks, rather than the roads (already legal in many places but work is needed in others)
They will be slow and light, so that if something goes seriously wrong and they hit you, they won’t injure you
They won’t hit you though, because they can come to a full stop in under a foot
You don’t need crumple zones, airbags or other passenger safety features for cargo, making them simple and inexpensive
How big is the last mile? It’s huge. It’s not just what today’s delivery companies do. Most deliveries are
actually made by customers who run out to stores to get stuff. The Starship robot will bring you things in less
time than a round-trip shopping trip would take, for less money, and with vastly less energy, pollution, traffic
congestion and parking. It’s a win for the store, the customer and for society.
It’s a really big win for those with disabilities or difficulty moving. The elderly are going to be able to live
in their own homes with greater independence even if shopping has become such a chore they were contemplating a
The robots will eventually create an “internet of parcels” (I guess the
term “internet of things” is already in use) where physical goods can move
around cities with an ease surpassed only by data. Not only will you be
able to buy anything, you’ll be able to rent things on short notice too,
or borrow them from your neighbours. The sharing economy can be enabled
and the meaning of ownership may change.
The convenience of robot delivery will surprise people. A common question I get asked is
“What does the robot do if you’re not home when it delivers?” and my answer is, “why would
you want the robot to deliver when you’re not home?” Regular delivery run’s on a driver’s
schedule, robotic delivery will run on yours. Robots don’t mind waiting either, so you
could ask a shop to put 5 pairs of shoes into a robot, and at home you could try them on and
put 4 pairs back in the robot and keep the ones you like.
I also expect interesting changes in prepared food. It will be possible to run a
“restaurant” inexpensively in a private kitchen and get ingredients and deliver
dishes quickly and cheaply with no wastage. A family might even order different
dishes from different locations to create a meal.
Nothing is 100% good for everybody — there will be disruption in the retail industry, and
retailers who exist primarily so you can go get things will have trouble competing
if they don’t embrace this model, but other retailers who are suffering from
competition from the online stores may find they can now dominate with fast
Of course, there might be competition in the air. Our students at Singularity University
were among the first to work on drone delivery with the Matternet project
which is beginning a trial delivering for the post office on the steep slopes of Switzerland.
Both methods face legal challenges, and both have their advantages. Drones will be faster and
can cover unusual terrain, while ground robots can carry more with less energy and have an easier
time landing. :-) I suspect people will tolerate small robots on their sidewalks more than
drones with heavy packages over their heads, but we’ll see.
Note that I’m a special advisor to Starship on both technology and business, but this post is
written with my own voice, and doesn’t speak on behalf of the company.
In the buzz over the Tesla autopilot update, a lot of commentary has appeared comparing this Autopilot with Google’s car effort and other efforts and what I would call a “real” robocar — one that can operate unmanned or with a passenger paying no attention to the road. We’ve seen claims that “Tesla has beaten Google to the punch” and other similar errors. While the Tesla release is a worthwhile step forward, the two should not be confused as all that similar.
Tesla’s autopilot isn’t even particularly new. Several car makers have had similar products in their labs for several years, and some have released it to the public, at first in a “traffic jam assist” mode, but reportedly in full highway cruise mode outside the USA. The first companies to announce it were Cadillac with the “Super Cruise” and VW’s “Temporary Autopilot” but they delayed that until much later.
Remarkably, Honda showed off a car ten years ago doing this sort of basic autopilot (without lane change) and sold only in the UK. They decided to stop doing that, however.
That this was actually promoted as an active product ten years ago will give you some clue it’s very different from the bigger efforts.
These cruise products require constant human supervision. That goes back to cruise control itself. With regular cruise control, you could take your feet off the pedals, but might have to intervene fairly often either by using the speed adjust buttons or full control. Interventions could be several times a minute. Later, “Adaptive Cruise Control” arose which still required you to steer and fully supervise, but would only require intervention on the pedals rarely on the highway. A few times an hour might be acceptable.
The new autopilot systems allow you to take your hands off the wheel but demand full attention. Users report needing to intervene rarely on some highways, but frequently on other roads. Once again, the product is useful if you only intervene once an hour, it might make your drive more relaxing.
Now look at what a car that drives without supervision has to do. Human drivers have an accident around every 2,500 to 6,000 hours, depending on what figures we believe. That’s a minor accident, and it’s after around 10 to 20 years of driving. A fatality accident takes place every 2,000,000 hours of driving — around 10,000 years for the typical driver. (It’s very good that it’s much more than a lifetime.)
If a full robocar needs an intervention, that means it’s going to have an accident, because there is nobody there to intervene. Just like humans, most of the errors that would cause an accident are minor. Running off the road. Fender benders. Not every mistake that could cause a crash or a fatality causes one. Indeed, humans make mistakes that might cause a fatality far more often than every 2,000,000 hours, because we “get away” with many of them.
Even so, the difference is staggering. A cruise autopilot like Tesla and the others have made is a workable product if you have to correct it a few times an hour. A full robocar product is only workable if you would need to correct it in decades or even lifetimes of driving. This is not a difference of degree, it is a difference of kind. It is why there is probably not an evolutionary path from the cruise/autopilot systems based on existing ADAS technologies to a real robocar. Doing many thousands times better will not be done by incremental improvement. It almost surely requires a radically different approach, and probably very different sensors.
To top it all off, a full robocar doesn’t just need to be this good, it needs a lot of other features and capabilities once you imagine it runs unmanned, with no human inside to help it at all.
The mistaken belief in an evolutionary path also explains why some people imagine robocars are many decades away. If you wanted evolutionary approaches to take you to 100,000x better, you would expect to wait a long time. When an entirely different approach is required, what you learn from the old approach doesn’t help you predict how the other approaches — including unknown ones — will do.
It does teach you something. By being on the road, Tesla will encounter all sorts of interesting situations they didn’t expect. They will use this data to train new generations of software that do better. They will learn things that help them make the revolutionary unmanned product they hope to build in the 2020s. This is a good thing. Google and others have also been out learning that, and soon more teams will.
Last night, one day early, I attended Stanford’s unveiling of their newest research vehicle for self-driving. In order to do experiments with drifting (where you let the rear wheels skid freely) they heavily modified an old Delorean.
They managed to get Jamie Hyneman of Mythbusters to host the event so there was a good crowd. He asked “Why a Delorean?” and instead of saying the obvious line:
“The way I see it, if you’re going to build a self-driving drifting car, why not do it with some style?”
They got into the actual technical reasons for it, even though they called the car Marty and were revealing it one day before “Back to the Future Day” — the day in the 2nd movie where Marty travels to in the future, Oct 21, 2015.
Back to the present, this car, with rear wheel drive and central engine mount is not a great car to drive, and they removed the engine and replaced it with dual electric motors from Renovo. This creates a car able to drive the two rear wheels independently. This offers the ability for the software to spin the wheels at different rates, and do things that no human driver could ever do, including special types of drifting. They already have managed to get the car to turn tighter doughnuts (circles) than a human could.
Drifting is usually done for show — it rarely will help you in a race. Hyneman actually showed that in one of the episodes of his show. Stanford’s team wants to answer whether the robot’s ability to do inhuman driving might offer more “outs” in a dangerous situation, like trying to avoid a collision. Might a car twist its wheels (perhaps some day all of its wheels) and spin them at different speeds to make the car take a path which could avoid an accident.
In effect, you would be trying to make a car that can drive like a Hollywood stunt car. In movies, stunt drivers often do fairly improbable and impossible moves with cars to avoid accidents. A classic Hollywood scene involves a car titling up in two wheels to get through a tiny gap it could not drive through. (The Stanford team did not propose this, and it’s a pretty hard thing to do, but it’s one way to envision the general idea.)
Up to now, research on accident avoidance has been fairly low-key. After all, the main task is to drive safely in the lane you are supposed to drive in. That’s plenty of work and the result of almost all of the focus. Eventually, teams will focus on what to do when things go wrong, but for now the prime priority is to make sure things don’t go wrong. Someday, they may even focus on the infamous trolley problem.
Normally, drifting is a bad idea. It means a loss of control and a loss of power. Normally, the connection of the tires and the road is the sole tool you have to drive and control a car. You would only give it up if you absolutely have to. Perhaps, the research will show, there are times you might want to.
Generally, drift or not, robots should become very good at avoiding accidents. They will know the physics of the tires perfectly, and they will calculate without panic, and will be able to drive with full confidence missing things by very thin margins while staying safe. While a human could not navigate a space only a few inches wider than the car with confidence, a robot could. A robot will always use the optimal combination of steering and braking, which humans need a lot of training to do. (Your tires can give you braking force or steering force but you must reduce one to get more of the other, so often the best strategy is to brake first and then steer, though the human instinct is to do both.)
The car is not super autonomous. It is meant to do test algorithms on private open spaces. It won’t be avoiding obstacles or plotting lanes on a highway. It will be testing how well a computer can get the most from the tires.
Tesla’s offering is not too different from what many other automakers have shown in what is sometimes called “highway cruise” — a combination of lanekeeping and adaptive cruise control, both of which have been around for a while. The vehicle reportedly insists you keep your hands touching the wheel, but some owners report you can take them off. Of particular note is the addition of lane-changing, which you can do by flicking the turn signal. You must check behind you, since if you attempt this when the next lane is moving fast and somebody is coming up on you quickly, you could cause a real problem if you don’t check. The vehicle won’t do the lane change if its blind spot detector sees an adjacent car, but it won’t stop you from cutting off somebody who is not in that zone and gaining on you.
I am curious about the claim that the system will “overtake” another car — I have not tried it out yet, but I presume since it should not change lanes on its own, user input will be required to command driving around another car. While you can’t safely make a lane change into a lane where you see no cars, you actually can make the change after passing a car because you know where that car is and that nothing is going to rush at you in the lane.
The release of this, and similar products will test a supposition I made earlier, that this products may not be as exciting as hoped. Worse, some drivers may find it a bit frightening trusting control to a vehicle knowing that from time to time they will need to grab the wheel. I have felt that myself driving in cars with adaptive cruise control, I am wondering if the ACC has seen the car stopped up ahead of me and will stop for it, since I see that before the radar or camera system does.
On the other hand, many people have reported that even though they must supervise, highway cruise can make the trip more relaxing, just as basic cruise control does. The trick is to get your brain into putting focus on its new sole task — supervisor — so that the rest of your brain can relax. With cruise control, you are reasonably able to have one part of your brain worry about steering, and relax the part that was going to worry about speed. So this may happen here.
More of a concern are the people who will trust it too much. Many of us already do crazy things, texting or playing with things on our phones when we are doing fully manual driving. It’s a given this will happen here. It will be safer to take your eyes from the road for a longer period than you should in a manual car, but people may magnify that. Yes, if you take your eyes off the road and the car ahead of you stops suddenly, the car will very probably brake for you — as will any car with forward collision avoidance. But not 100% of the time, and that’s the rub if you trust it to.
I may have more to say after taking a ride in one of these. I think the first really interesting product won’t be this, but a more full-auto traffic jam assist, that will drive for you in a traffic jam and allow you to take your attention off the road entirely to read or work on your phone or computer. At the low speeds of a traffic jam, boxed in by other cars, the driving problem is much simpler. You don’t even need to see the lanes, just follow the cars. If the car in front of you zooms ahead, the traffic jam is over, and the driver needs to manually speed the car up. Done at low speeds, that transition can be fairly safe, and in addition, if the driver does nothing and the car slows to a halt, that is not unsafe — just annoying — in a breaking up traffic jam. The main remaining problem in traffic jams is what to do when the cars in front of you change lanes. Are they turning just to go into another lane, or is it because all the lanes are turning due to restriping (common in jams) or an obstacle. You need to get that right, and let the driver know about it, but you can’t buzz the driver every time somebody does a lane change or the product is not useful.
Several car vendors (and probably Tesla) have been working on this, and could release it quite soon, if they get the guts and legal approval to do so.
Tesla may get more attention for the way they delivered these new features, as an over the air software update. Telsa has now done this several times, and promised it would do this, but from the viewpoint of traditional car makers, it is incredibly radical. In the modern computerized car, like the phone, regular software updates are just part of the system. This is going to be mostly positive, but will create some issues when the time comes for a “recall” of some electronic function of a car. Today when that happens, the car company mails all the owners and says, “Please come in to your dealer to get new firmware for your ECU to fix the problem.” From that point, it is the owner’s responsibility to get the update done. Tesla can send a fix over the air, but that means it can’t pass responsibility on to the owners. Some day, a company is going to find a problem in their self-drive system that clearly should be fixed, but won’t have the fix ready to go for weeks. It will face the question of what to do in those intervening weeks. Will it be forced to turn off the system it now knows to have a flaw? Or can it tell owners, “We know we have this flaw, if you want to drive, it’s your responsibility now.”
During a very busy September of travel, I let a number of important stories fall through the cracks. The volume of mainstream press articles on Robocars is immense. Most are rehashes of things you have already seen here, but if you want the fastest breaking news, there are now some sources that focus on that. Here I will report the important news with analysis.
Earlier we learned that Google restructured itself and put the car project in the new Alphabet Holding company. Google also hired John Krafcik to lead the project. Krafcik is a car industry veteran from Hyundai, Ford and Truecar but what’s interesting is he’s been announced as “CEO,” which strongly implies that the project will be spun out as a subsidiary as I suspected, with freedom to be its own company. Chris Urmson has led the project since Sebastian Thrun moved on to Udacity, but the bulk of the work has been engineering, which Chris will continue to lead. This is a good move, one person probably should not do both. (Chris did do a great job on the recent 60 minutes, though.)
Google continues to state it does not wish to be a carmaker, and will work with existing carmakers.
Mercedes and BMW not selling cars
Perhaps the biggest news comes in announcements from both BMW and Mercedes that they plan to investigate selling rides instead of cars. They both own large car-sharing systems (DriveNow and Car2Go respectively) which rent cars one way by the minute, but while they are large for the industry, they are tiny portions of these companies. However, the idea that these companies, with a century of being about selling cars and nameplate luxury to consumers who drive away in them, can think seriously of being like Uber is a sign we’re in the 21st century. BMW and Mercedes are not idiots — they have always known this was a potential business plan. The hard part at a big company is having the guts and leadership to turn the company 90 degrees if it needs to be done.
Mercedes prototype has the name “Car2Come” — a car that delivers itself to you and you drive it. They understand that name doesn’t really sound that great in the US market. :-) Longtime readers will recognize this as similar to what I called a whistlecar in 2007.
Apple clues keep showing up
Apple refuses to say anything, but little clues keep emerging, including records of Apple’s request to use an old military base converted into a robocar test track in Northern California, and also talking to the DMV’s crew about robocars. Other leaks suggest with certainty that Apple project Titan is building an electric car (due in 2019) and that making it self-driving is on the table, but not the #1 priority.
After Uber raided some of the top people from CMU’s robotics labs (it should be noted that Chris Urmson and Sebastian Thrun also came out of that lab) they have been donating money back to fund more research inside the school, and also at the University of Arizona.
Uber remains one of the biggest game-changers out there. Aside from their money and unconventional thinking, and of course the world’s #1 brand in selling rides, Uber also has the easiest path to collecting vast volumes of driving data at low cost, and data are important.
Toyota and Honda make announcements
The Japanese have been surprisingly behind, except for Nissan, but now Honda has finally made some serious steps getting permits for California, and Toyota has announced both new projects, and has joined on the popular goal of 2020, saying that Toyota cars will be driving the public around at the 2020 Olympics in Tokyo.
Some other companies have also joined the game, such as Citroën, which had a car drive to the recent ITS World Congress in Bordeaux.
In the Shuttle business, Navia is back as the Navya, and the new vehicle is more enclosed, as shown in this video. Many other private campus shuttle projects are heating up around the world, including Citymobil2. Easymile (also from France) is setting up a pilot project in the Bay Area and shuttle projects are underway in many labs and towns around the world. (Disclaimer: I am discussing involvement in one of them which I will talk about later.)
The news goes on
The volume of news stories shows why Gartner put robocars so high on their hype cycle. I have not covered a lot of other news, including:
New states, provinces and countries passing new laws or enabling testing. Even my own home province of Ontario.
The creation of new test tracks and facilities — these are useful but as news they are mostly PR
