Today sees the un-stealthing of a new company called Otto which plans to build self-driving systems for long haul trucks. The company has been formed by a skilled team, including former members of Google's car team and people I know well. You can see their opening blog post

My entire focus on this blog, and the focus of most people in this space, has been on cars, particularly cars capable of unmanned operation and door-to-door service. Most of those not working on that have had their focus on highway cars and autopilots. The highway is a much simpler environment so much easier to engineer, but it operates at higher speeds so the cost of accidents is worse.

That goes doubly true for trucks that are fast, big and massive. At the same time, 99% of truck driving is actually very straightforward -- stay in a highway lane, usually the slow one, with no fancy moving about.

Some companies have done exploration of truck automation. Daimler/Freightliner has been testing trucks in Nevada. Volvo (trucks and cars together) has done truck and platooning experiments, notably the Sartre project some years ago. A recent group of European researchers did a truck demonstration in the Netherlands, leading up to the Declaration of Amsterdam which got government ministers to declare a plan to modify regulations to make self-driving systems legal in Europe. Local company Peloton has gone after the more tractable problem of two-truck platoons with a driver in each truck, aimed primarily at fuel savings and some safety increases.

Safety

While trucks are big and thus riskier to automate, they are also risky for humans to drive. Even though truck drivers are professionals who drive all day, there are still around 4,000 killed every year in the USA in truck accidents. More than half of those are truck drivers, but a large number of ordinary road users are also killed. Done well, self-driving trucks will reduce this toll. Just as with cars, companies will not release the systems until they believe they can match and beat the safety record of human drivers.

The Economics

Self-driving trucks don't change the way we move, but they will have a big economic effect on trucking. Driver pay accounts for about 25-35% of the cost of truck operation, but in fact early self-driving won't take away jobs because there is a serious shortage of truck drivers in the market -- companies can't hire enough of them at the wages they currently pay. It is claimed that there are 50,000 job openings unfilled at the present time. Truck driving is grueling work, sometimes mind-numbing, and it takes the long haul driver away from home and family for over a week on every long-haul run. It's not very exciting work, and it involves long days (11 hours is the legal limit) and a lot of eating and sleeping in truck stops or the cabin of the truck.

Average pay is about 36 cents/mile for a solo trucker on a common route. Alternately, loads that need to move fast are driven by a team of two. They split 50 cents/mile between them, but can drive 22 hours/day -- one driver sleeps in the back while the first one takes the wheel. You make less per mile per driver, but you are also paid for the miles you are sleeping or relaxing.

A likely first course is trucks that keep their solo driver who drives up to 11 hours -- probably less -- and have the software drive the rest. Nonstop team driving speed with just one person. Indeed, that person might be an owner-operator who is paying for the system as a businessperson, rather than a person losing a job to automation. The human would drive the more complex parts of the route (including heavy traffic) while the system can easily handle the long nights and sparse heartland interstate roads.

The economics get interesting when you can do things that are expensive for human drivers and teams. Aside from operating 22 or more hours/day at a lower cost, certain routes will become practical that were not economic with human drivers, opening up new routes and business models.

The Environment

Computer driven trucks will drive more regularly than humans, effectively driving in "hypermile" style as much as they can. That should save fuel. In addition, while I would not do it at first, the platooning experimented with by Peloton and Sartre does result in fuel savings. Also interesting is the ability to convert trucks to natural gas, which is domestic and burns cleaner (though it still emits CO2.) Automated trucks on fixed routes might be more willing to make this conversion.

Road wear

There is strong potential to reduce the damage to roads (and thus the cost of maintaining them, which is immense and seriously in arrears) thanks to the robotruck. That's because heavy trucks and big buses cause almost all the road wear today. A surprising rule of thumb is that road damage goes up with the 4th power of the weight per axle. As such an 80,000lb truck with 34,000lb on two sets of 2 axles and 6,000lb on the front axle does around 2,000 times the road damage of a typical car!

A week ago, a rather strange event took place. No, I'm not talking about just the Transit of Mercury in front of the sun on May 9, but an odd result of it.

My recent efforts in consulting and speaking have led to a lot more travel -- which is great sometimes, but also often a drain. I've been staying in so many hotels that I thought it worth enumerating some of the things I think every hotel room should have, and what I often find missing.

Most of these things are fairly inexpensive to do, though a few have higher costs. The cheaper ones I would hope can be just included, I realize some might incur extra charges or a slightly more expensive room, or perhaps they can be offered as a perk to loyalty program members.

Desk space for all occupants

Most rooms usually only have a workspace for one, even if it's a double room. The modern couple both have computers, and both need a place to work, ideally not crammed together. That's also true when two co-workers share a room. And in a perfect room, both desk spaces share the other attributes of a good desk, namely:

• The surface is not glass. I would say more than half the desks in hotel rooms are glass, which don't work well with optical mice. Sure, you put down some papers, but this seems kinda silly.
• Of course, 2 or even 3 power outlets, on the desk or wall above it. Ideally the "universal" kind that accept most of the world's plugs. (Sure, I bring adapters but this is always handy.) Don't make me crawl under the desk to plug things in, have to unplug something else.

To my horror, Marriott has been building some new hotels with no desk space at all. Some person (I would say some idiot) decided that since millennials use fewer laptops and just want to sit on a couch with their tablet, it was better to sacrifice the desk. Those hotels had better have folding desks you can borrow, in fact all hotels could do that to fix the desk space shortage, particularly if rooms are small. Another option would be a leaf that folds down from the wall.

Surfaces/racks for luggage and other things for everybody.

Many rooms are very lacking in table or surface space beyond the desk. Almost every hotel room comes with only one luggage holder, where a couple might find themselves with 3 or in rare case 4 bags. I doubt these folding luggage holders are that expensive, but if you can't put more than one in every room, then watch people as they check in, and note how many bags they have, and have somebody automatically send up some extra holders to their room. At the very least make it easy for them to ask. I mean these things are under $30 quantity one. Get more!

Bathrooms need surface space, too. Too often I've seen sinks with nowhere to put your toiletries and freedom bag. In fact, I want space everywhere to unpack the things I want to access.

Power by the bed (and other places)

Sure, I get that older hotel rooms did not load up with power outlets, and modern ones do. But aside from the desk, most people want power by the bed now, for their phone charger if nothing else. If you just have one plug by the bed, put a 3-way splitter (global plug, of course) on that plug so that people can plug things in without unplugging the light or clock. And ideally up high, so I don't have to crawl behind things to get at it.

A little more controversial is the idea of offering USB charging power. Today, we all carry chargers, but the hope is that if charging becomes commonplace, then like the travel hair dryer people used to carry and no longer do, we might be able to depend on finding a charger. Problem is, charging standards are many and change frequently -- we now have USB regular (useless) and fast-charge, along with Qualcomm quick-charge and USB C. More will come. On top of this, strictly you should not plug your device into a random USB port which might try to take it over. You can get what's called a "USB Condom" to block the data lines, but those might interfere with the negotiation phase of smarter power standards. A wireless "Qi" charging plate could be a useful thing.

As a couple, we have had up to 8 things charging at the same time, when you include phones, cameras, external batteries, headphones, tablets and other devices. So I bring a 5-way USB fast charger and rely on laptops or other chargers to go the distance.

Let me access the HDTV as a monitor, or give me a monitor.

Some rooms block you from any access to the TV. Some have a VGA or HDMI port built into a console on the desk. The latter is great, but usually the TV is mounted in a way that makes it not very useful as a computer monitor for working. It's primarily useful for watching video. I pretty much never watch video in a hotel room, so given the choice, I would put the monitor by the desk, and it should be 1080p or better -- in fact 4K should be the norm for any new installations. If you don't have one, have one I can call down for, even at a modest fee.

A recent news story from Utah describes a Tesla which entered self-park ("summon") mode and drive itself into the back of a flatbed truck raises some interesting issues.

If you had asked me recently what big car company was the furthest behind when it came to robocars, one likely answer would be Fiat-Chrysler. In fact, famously, Chrysler ran ads several years ago during the superbowl making fun of self-driving cars and Google in particular:

I have often written on the challenge facing existing automakers in the world of robocars. They need to learn to completely switch their way of thinking in a world of mobility on demand, and not all of them will do so. But they face serious challenges even if they are among the lucky ones who fully "get" the robocar revolution, change their DNA and make products to compete with Google and the rest of the non-car companies.

While I'm very excited about the coming robocar world, there are still many unsolved problems. One I've been thinking about, particularly with my recent continued thinking on transit, is how to provide robotaxi service to the poor, which is to say people without much money and without credit and reputations.

In particular, we want to avoid situations where taxi fleet operators create major barriers to riding by the poor in the form of higher fees, special burdens, or simply not accepting the poor as customers. If you look at services like Uber today, they don't let you ride unless you have a credit card, though in some cases prepaid debit cards will work.

Today a taxi (or a bus or Uber style vehicle) has a person in it, primarily to drive, but they perform another role -- they constrain the behaviour of the rider or riders. They reduce the probability that somebody might trash the vehicle or harass or be violent to another passenger.

Of course, such things happen quite rarely, but that won't stop operators from asking, "What do we do when it does happen? How can we stop it or get the person who does it to pay for any damage?" And further they will say, "I need a way to know that in the rare event something goes wrong, you can and will pay for it." They do this in many similar situations. The problem is not that the poor will be judged dangerous or risky. The problem is that they will be judged less accountable for things that might go wrong. Rich people will throw up in the back of cars or damage them as much as the poor, perhaps more; the difference is there is a way to make them pay for it. So while I use the word poor here, I really mean "those it is hard to hold accountable" because there is a strong connection.

As I have outlined in one of my examinations of privacy a taxi can contain a camera with a physical shutter that is open only between riders. It can do a "before and after" photograph, mostly to spot if you left items behind, but also to spot if you've damaged or soiled the vehicle. Then the owner can have the vehicle go for cleaning, and send you the bill.

But they can only send you the bill if they know who you are and have a way to bill you. For the middle class and above, that's no problem. This is the way things like Uber work -- everybody is registered and has a credit card on file. This is not so easy for the poor. Many don't have credit cards, and more to the point, they can't show the resources to fix the damage they might do to a car, nor may they have whatever type of reputation is needed so fleet operators will trust them. The actions of a few damn the many.

The middle class don't even need credit cards. Those of us wishing to retain our privacy could post a bond through a privacy protecting intermediary. The robotaxi company would know me only as "PrivacyProxy 12323423" and I would have an independent relationship with PrivacyProxy Inc. which would accept responsibility for any damage I do to the car, and bill me for it or take money from my bond if I'm truly anonymous.

Options for the poor

Without the proxy, robotaxi operators will want some sort of direct accountability from passengers for any problems they might cause. Even for the middle class, it mostly means being identified, so if damage is found, you can be tracked down and made to pay. The middle class have ability to pay, and credit. The poor don't, at least many of them don't.

People with some level of identity (an address, a job) have ways to be accountable. If the damage rises to the level where refusing to fix it is a crime at some level, fear of the justice system might work, but it's unlikely the police are going to knock on somebody's door for throwing up in a car.

In the future, I expect just about everybody of all income levels will have smartphones, and plans (though prepaid plans are more common at lower income levels.) One could volunteer to be accountable via the phone plan, losing your phone number if you aren't. Indeed, it's going to be hard to summon a car without a phone, though it will also be possible using internet terminals, kiosks and borrowing the phones of others.

More expensive rides

A likely solution, seen already in the car rental industry, is to charge extra for insurance for those who can't prove accountability another way. Car rental company insurance is grossly overpriced, and I never buy it because I have personal insurance and credit cards to cover such issues. Those who don't often have to pay this higher price.

It's still a sad reality to imagine the poor having to pay more for rides than for the rich.

An option to mitigate this might be cars aimed at carrying those who are higher risk. These cars might be a bit more able to withstand wear and tear. Their interiors might be more like bus interiors, easily cleaned and harder to damage, rather than luxury leather which will probably be only for the wealthier. To get one, you might have to wait longer. While a middle-class customer ordering a cheap car might be sent a luxury car because that's what's spare at the time, it is less likely an untrusted and poor customer would get that.

Before we go do far, I predict the cost of robotaxi rides will get well below $1/mile, heading down to 30 cents/mile. Even with a 30% surcharge, that's still cheaper than what we have today, in fact it's cheaper than a bus ticket in many towns, certainly cheaper than an unsubsidized bus ticket which tends to run $5-$6. Still my hope for robotaxi service is that it makes good transportation more available to everybody, and having it cost more for the poor is a defect.

In addition, as long as damage levels remain low, as a comment points out, perhaps the added cost on every ride would be small enough that you don't need worry about this for poor or rich. (Though having no cost to doing so does mean more spilled food, drink and sadly, vomit.)

Reputation

Over time, fortunately, poor riders could develop reputations for treating vehicles well. Build enough reputation and you might have access to the same fleet and prices that the middle class do, or at least much cheaper insurance. Cause a problem and you might lose the reputation. It would be possible to build such a reputation anonymously, though I suspect most people and companies would prefer to tie it to identity, erasing privacy. Anonymous reputations in particular can be sold or stolen which presents an issue. One option is to tie the reputation to a photo, but not a name. When you get in the car, it would confirm you match the photo, but would not immediately know your name. (In the future, though, police and database companies will be able to turn the photo into a name easily enough.)

Poor riders would still have to pay more to start, probably, or suffer the other indignities of the lower class ride. However, a poor rider who develops a sterling reservation might be able to get some of that early surcharge back later. (Not if it's insurance. You can't get insurance back if you don't use it, it doesn't work that way!)

It could also be possible for the poor to get friends to vouch for them and give them some starter reputation.

Unfortunately, poor who squander their reputation (or worse, just ride with friends who trash a car) could find themselves unable to travel except at high cost they can't afford. It could be like losing your car.

The government

The government will have an interest in making sure the poor are not left out of this mobility revolution. As such, there might be some subsidy program to help people get going, and a safety net for loss of reputation. This of course comes with a cost. Taxes would pay for the insurance to fix cars that are damaged by riders unable to be held accountable.

The alternative, after all, is needing to continue otherwise unprofitable transit services with human drivers just for the sake of these people who can't get private robocar rides. Transit may continue (though without human drivers) at peak times, but it almost surely vanishes off-peak if not for this.

Recently a reddit user posted this short video of an amazingly lucky driver in Japan who was able to turn his car around just in time to escape the torrent of the tsunami.

The question asked was, how would a robocar deal with this? It turns out there are many answers to this question. For this particular question, as you'll see by the end, the answer is probably "very well."

My recent article on a future vision for public transit drew some ire by those who viewed it as anti-transit. Instead, the article broke with transit orthodoxy by suggesting that smaller vehicles (including cars and single person pods) might produce more efficient transit than big vehicles. Transitophiles love big vehicles for reasons beyond their potential efficiency, so it's a hard sell.

Let's look at the factors which determine what vehicle size makes the best transit.

Perhaps the world's most exciting new technology today are deep neural networks, in particular the convolutional neural networks such as "Deep Learning." These networks are conquering some of the most well known problems in artificial intelligence and pattern matching, and since their development just a few years ago, milestones in AI have been falling as computer systems that match or surpass human capability have been demonstrated. Playing Go is just the most recent famous example.

This is particularly true in image recognition. Over the past several years, neural network systems have gotten better than humans at problems like recognizing street signs in camera images and even beating radiologists at identifying cancers in medical scans.

These networks are having their effect on robocar development. They are allowing significant progress in the use of vision systems for robotics and driving, making those progress much faster than expected. 2 years ago, I declared that the time when vision systems would be good enough to build a safe robocar without lidar was still fairly far away. That day has not yet arrived, but it is definitely closer, and it's much harder to say it won't be soon. At the same time, LIDAR and other sensors are improving and dropping in price. Quanergy (to whom I am an advisor) plans to ship $250 8-line LIDARS this year, and $100 high resolution LIDARS in the next couple of years.

The deep neural networks are a primary tool of MobilEye, the Jerusalem company which makes camera systems and machine-vision ASICs for the ADAS (Advanced Driver Assistance Systems) market. This is the chip used in Tesla's autopilot, and Tesla claims it has done a great deal of its own custom development, while MobilEye claims the important magic sauce is still mostly them. NVIDIA has made a big push into the robocar market by promoting their high end GPUs as the supercomputing tool cars will need to run these networks well. The two companies disagree, of course, on whether GPUs or ASCICs are the best tool for this -- more on that later.

In comes comma.ai

In February, I rode in an experimental car that took this idea to the extreme. The small startup comma.ai, lead by iPhone hacker George Hotz, got some press by building an autopilot similar in capability to many others from car companies in a short amount of time. In January, I wrote an introduction to their approach including how they used quick hacking of the car's network bus to simplify having the computer control the car. They did it with CNNs, and almost entirely with CNNs. Their car feeds the images from a camera into the network, and out from the network come commands to adjust the steering and speed to keep a car in its lane. As such, there is very little traditional code in the system, just the neural network and a bit of control logic.

Here's a video of the car taking us for a drive:

The network is built instead by training it. They drive the car around, and the car learns from the humans driving it what to do when it sees things in the field of view. To help in this training, they also give the car a LIDAR which provides an accurate 3D scan of the environment to more absolutely detect the presence of cars and other users of the road. By letting the network know during training that "there is really something there at these coordinates," the network can learn how to tell the same thing from just the camera images. When it is time to drive, the network does not get the LIDAR data, however it does produce outputs of where it thinks the other cars are, allowing developers to test how well it is seeing things.

This approach is both interesting and frightening. This allows the development of a credible autopilot, but at the same time, the developers have minimal information about how it works, and never can truly understand why it is making the decisions it does. If it makes an error, they will generally not know why it made the error, though they can give it more training data until it no longer makes the error. (They can also replay all other scenarios for which they have recorded data to make sure no new errors are made with the new training data.)

For many years, I have been using RAID for my home storage. With RAID (and its cousins) everything is stored redundantly so that if any disk drive fails, you don't lose your data, and in fact your system doesn't even go down. This can come at a cost of anywhere from about 25% to 50% of your disk space (but disk is cheap) and it also often increases disk performance. Some years ago I wrote about how disk drives should be sold in form factors designed for easy RAID in every PC, and I still believe that.

I frequently see people claim that one effect of robocars is that because we'll share the cars (when they work as taxis) and most cars stay idle 95% of the time, that a lot fewer cars will be made -- which is good news for everybody but the car industry. I did some analysis of why that's not necessarily true and recent analysis shows the problem to be even more complex than I first laid out.

To summarize, in a world of robotic taxis, just like today's taxis, they don't wear out by the year any more, they wear out by the mile (or km.) Taxis in New York last about 5 years and about 250,000 miles, for example. Once cars wear out by the mile, the number of cars you need to build per year is equal to:

Total Vehicle Miles per year
Avg Car Lifetime in Miles

As you can see, the simple equation does not involve how many people share the vehicle at all! As long as the car is used enough that the car isn't junked before it wears out from miles, nothing changes. It's never that simple, however, and some new factors come into play. The actual model is very complex with a lot of parameters -- we don't know enough to make a good prediction.

People travel more in cars.

It's likely that the number of miles people want to travel goes up for a variety of reasons. Robocars make car travel much more pleasant and convenient. Some people might decide to live further from work now that they can work, read, socialize or even sleep on the commute. They might make all sorts of trips more often. Outside of rush hour, they might also be more likely to switch from other modes, such as public transit, and even flying. Consider two places about a 5 hour drive apart -- today flying is going to take just under 3 hours due to all the hassles we've added to flying, even with the improvements robocars make to those hassles. Many might prefer an uninterrupted car ride where they can work, watch videos or sleep.

Vehicles run empty to reposition

Regular taxis have wasted miles between rides. Indeed, a New York taxi has no passenger 38% of the time. Fortunately, robocars will be a lot more efficient than that, since they don't need to cruise around looking for rides. Research suggests a more modest 10% "empty mile" cost, but this will vary from situation to situation. If you need the robotaxi fleet to constantly run empty in the reverse commute direction, it could get worse. Among those who believe robocars will be more personally owned than used as taxis, we often see a story painted of how a household has a car that takes one person to work, and returns home empty to take the 2nd person, and then returns again to take others on daytime errands. This is possible, but pretty inefficient. I think it's far more likely that in the long term, such families will just use other taxi services rather than have their car return home to serve another family member.

Cars last longer

The bottom part of the equation is likely to increase, which reduces the number of cars made. Today, cars are engineered for their expected life-cycle -- 19 years and 190,000 miles in California, for example. Once you know your car is going to have a high duty cycle, you change how you engineer it. In particular, you combine engineering of parts for your new desired life cycle with specific replacement schedules for things that will wear out sooner. You want to avoid junking a car with lots of life in the engine just because the seats are worn out, so you make it easy to replace the seats, and you have the car bring itself to a service center where that's fast and easy.

General Motors has purchased "Cruise," a small self-driving startup in San Francisco. Rumours suggest the price was over one billion dollars. In addition, other rumours have come to me suggesting that at least one other startup has been seeking a new round of funding at that valuation, but did not succeed due to the market downturn.

Michael Bloomberg, a contender for an independent run for US President has announced he will not run though for a reason that just might be completely wrong. As a famous moderate (having been in both the Republican and Democratic parties) he might just have had a very rare shot at being the first independent to win since forever.

Here's why, and what would have to happen:

1. Donald Trump would have to win the Republican nomination. (I suspect he won't, but it's certainly possible.)
2. The independent would have to win enough electoral votes to prevent either the Republican or Democrat getting 280.

If nobody has a majority of the electoral college, the house picks the President from the top 3 college winners. The house is Republican, so it seems pretty unlikely it would pick any likely Democratic Party nominee, and the Democrats would know this. Once they did know this, the Democrats would have little choice but to vote for the moderate, since they certainly would not vote for Trump.

Now all it takes is a fairly small number of Republicans to bolt from Trump. Normally they would not betray their own party's official nominee, but in this case, the party establishment hates Trump, and I think that some of them would take the opportunity to knock him out, and vote for the moderate. If 30 or more join the democrats and vote for the moderate, he or she becomes President.

It would be different for the Vice President, chosen by the senate. Trump probably picks a mainstream republican to mollify the party establishment, and that person wins the senate vote easily.

To be clear, here the independent can win even if all they do is make a small showing, just strong enough to split off some electors from both other candidates. Winning one big state could be enough, for example, if it was won from the candidate who would otherwise have won.

Reports released reveal that one of Google's Gen-2 vehicles (the Lexus) has a fender-bender (with a bus) with some responsibility assigned to the system. This is the first crash of this type -- all other impacts have been reported as fairly clearly the fault of the other driver.

I have a big article forthcoming on the future of public transit. I believe that with the robocar (and van) it moves from being scheduled, route-based mass transit to on-demand, ad-hoc route medium and small vehicle transit. That's in part because of the disturbingly poor economics of current mass transit, especially in the USA. We can do much better.

Last year, I wrote a few posts on the attack on Science Fiction's Hugo awards, concluding in the end that only human defence can counter human attack. A large fraction of the SF community felt that one could design an algorithm to reduce the effect of collusion, which in 2015 dominated the nomination system.

I've written before about my experiences inhabiting a telepresence robot. I did it again this weekend to attend a reunion, with a different robot that's still in prototype form.

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.
