Robocars & More

Every time I compare Tesla with other contenders, people will say things to the effect of "they don't count, they use maps so they can only drive in tiny regions" because they think that's a bug rather than a feature.

Maps are super useful, and a car that can try to drive without a map is a car that can make a map, and so maps scale just fine and help you drive more roads, rather than fewer.

So I made a video outlining the virtues of maps, why they are cheap, and why it's OK if construction changes the road after you map it.

There isn't usually too much learned from these reports, but we can compare year to year, so here are some things learned this time:

California Disengagement Reports tell us a little more

The feds (NHTSA) are forcing Tesla to do a recall (software update, really) to disable the ability for the FSD prototype to do rolling stops at empty intersections. That turns out to be a surprising bold exercise of regulatory power, and probably a terrible idea, no matter how bad Tesla is. (Almost.) Full details in a new column on the situation, but there's a ton of nuance to this.

A frequent lament is that the design of the US constitution has created a system where voters are highly unequal. Most of all this is seen in the Senate, where the nearly 40 million residents in California have 2 seats in the Senate, and so do 550,000 in Wyoming. Indeed, if you take the 20 smallest states, they have fewer people together than California and get 40 seats in the Senate compared to the two. That same fact also means a smaller but real bias in the electoral college, with the smaller states having a bit more say in how the

It doesn't get as much coverage as others, but MobilEye has amassed an impressive portfolio of components to give them a shot at the robotaxi and robocar world (one of the few with a shot at both.)

Today I release both a new article with my analysis of their strategy and components, and also a video I made of an interview with Amnon Shashua, the founder and CEO of MobilEye, which is now a unit of Intel but will be spun out soon as a public company again.

Last week saw Optimus Ride get sold for acqui-hire, and Local Motors shutting its doors. There are reasons why self-driving shuttles aren't that interesting right now, but that's going to change, and small van-sized vehicles are probably the future of group transportation.

You've seen Wordle, the game sweeping the web. I built a tool to examine all the choices and pick the best starting word, and then help you pick your 2nd word after you get the result.

Well, I finally got to try Tesla FSD, and it was a big disappointment. From a robocar developer's viewpoint, it sucks and I give it an F.

I made a video review and a text one. The text one contains the review part of the video and lots more information. The video has the 3.5 mile sample ride around Apple HQ, full of mistakes.

Here's my annual countdown of the biggest stories in self-driving for 2021. This year I have a summary of my text stories, and also made a video countdown because there's lots of nice background video to use.

You can read the text version on the Forbes site at:

Airlines have removed change fees on many flights, a trend started by the pandemic. Everybody has wished to get more flexibility in airline ticket pricing and changing, though airlines want to squeeze out every dollar that every passenger can afford. The new trends in flexible work may allow an option to please both sides with tickets that allow the airline to change when you fly to fill seats in exchange for a lower price and easier changes.

I wrote before about the accursed "beep beep" that big machines make when they back up -- and even a few cars. There is an answer to it, and that answer has just come out of patent. So what can we do to ban the beep and make safer systems that don't destroy the peace and quiet of the air?

Read about that in this Forbes.com story at We cam finally do away with the accursed beep-beep

In a short period we saw 3 at-fault accidents involving robocars (with one being purely the fault of the safety driver) and we're going to see more. We're going to have to learn how to deal with them, to tell the difference between serious error that says a team has deployed too early, and the accidents that will happen with miles because perfection is not a possible goal.

The overwhelming of the vote of the World Science Fiction Society to send the 2023 convention to China created controversy and not for the first time. They had a similar problem with the Hugo award nomination process which is even easier to overwhelm with a much smaller concerted group. They solved this problem by making the nomination rules much more complex, with an algorithm to attempt to de-rank candidates that appear in "slates" on many ballots.

I have often written about the debate between the robotaxi vision of self-driving and the private car sales vision. That debate got writ large last week with the firing of Cruise CEO Dan Ammann over his desire to push the robotaxi vision (and some other differences of view.)

I write about it on Forbes.com in GM CEO Mary Barra fires Cruise CEO over robotaxi/car sales battle

I used to be a lot more involved in the annual science fiction Worldcon and the Hugo awards, but have drifted away of late. One of the reasons is that, even more than before, they have become more about politics than science fiction or community. There was a huge controversy over an attempt at bloc voting to change the Hugo awards, which both succeeded and failed, and had somewhat faded into the past. But the intrigues continue.

Mercedez-Benz has announced approval of their “Drive Pilot” system, in Germany. Tesla, on the other hand, doesn't do this because of their focus on the far-off goal of a "full" self-driving product. What does a traffic jam pilot really mean, and what could Tesla be doing if they weren't putting so much focus on the still far-off FSD?

I consider this my my new Forbes site article Mercedes Gets Approval For Traffic Jam Pilot, Where Is Tesla?

How can we tell how far along a robotaxi project is? They don't let us look under the hood, so we have to observe their real bets and milestones.

I've made a list of a rough order for the milestones. Most teams have far to go.

In an earlier article, I noted that Cruise, in demonstrating their first robotaxi rides with no safety driver, did all the pick-up an drop-off by just stopping in the lane (late at night.) This is something many Uber drivers do as well, but it's not technically legal. Cruise is doing things one step at a time, but the SF MTA doesn't like that and filed an opposition to them getting a permit to operate the service with the public (currently they just do employees.)

Here's a Forbes.com article on the issues with doing pick-up and drop-off.

I've tended to downplay the early e-VTOL designs that are essentially big multirotor drones for people, including Volocopter. But the reality is that these designs, while losers in the long run, are winning the early race because they can get approved and in the air sooner. Here's an examination of Volocopter and what may happen long term.

Volocopter's simple "drone" design may end up a winner

Posted last week was my Forbes site story on Waymo's no imaging radar. They don't give a lot of details, but I explain what it means:
