(This originally appeared on Forbes.com. I am not always linking stories from there as they now have their own comment section though it is not well used as yet.)

An annoying paper argues that self-driving cars will use huge amounts of compute and thus have a giant carbon footprint. The boring way that it's wrong is that the compute load will not grow as they suggest.

The more interesting way that it's wrong is that self-driving EVs will draw most of their power from no-emission generation sources like solar and nuclear, even if they do use a lot of power.

I recently took a ride in a fully autonomous Waymo vehicle in San Francisco. It was my first ride in many years — I had been a member of the early team while it was part of Google. My guide on the ride was Andrew Chatham, whom I had worked with back then. He is now a Distinguished Engineer, managing fleet logistics and many other things, and reporting directly to Waymo’s co-CEO.

I have started building a map of all the autonomous services deployed carrying passengers or cargo. The services must be available to the public and out in public or semi-public spaces.

Turns out there are a lot. Contributions are welcome.

I believe a new course should be added to the curriculum for teens. It would be a course on critical thinking skills, covering all the ways people will try to fool you and tricks of the human mind, to arm students against these traps.

Here's my annual summary of the top stories of the prior year. This time the news was a strong mix of bad and good.

And see the video version here:

California recently passed a law that is obviously aimed at forcing Tesla to stop using the name “Full Self-Driving” to describe the expensive software add-on they sell for their cars which does not, at this time, provide self driving, full or otherwise. The ostensible reason for this is to avoid customer confusion and the potential danger that could come from people thinking they have a self-driving car when they don’t.

Many companies are working on self-driving trucks and delivery. As it became clear that robotaxi required a very large investment, teams looked for a more tractable problem. Most have gone after long-haul trucking on the interstate, but one leader has quietly gone after the “middle mile” while others go after long-haul and last-mile.

Cruise and Waymo, the clear #2 and #1 (respectively) in the Robotaxi race, have recently expanded their service areas for public access rides and driving with nobody in the vehicle. It’s a continued positive milestone in a year that has seen many setbacks for self-driving projects.

Musk himself was surprised to see how controversial he had become when he got a lot of booing on stage with Dave Chappelle in San Francisco last night.

Musk has always been somebody who refused to give a crap what other people think, because he can afford it. But now that his personal brand is so tied to the success of both Tesla and Twitter, he has to deal with the fact that personal brand is largely what other people think.

Analysis of this problem, and how it affects the success and stock price of Tesla, is in this new article on the Forbes site:

Here's a digest of some of my recent postings on Forbes.com

Tesla may add radar back

A filing suggests Tesla may be putting a radar back in their cars, but this time a high resolution radar, which is a bit like the LIDAR they swore was a crutch. It would be a good idea.

Generally it doesn't make sense (and isn't that green) to have off-grid solar compared to grid-tied solar. However, a new company sells a self-contained solar EV charging station for parking lots which they claim is cheaper than on-grid, because you can just get it delivered in one day with no permits, planning, wiring or construction.

It's true that all those factors are now the biggest element of charging and solar installations.

A recent Tweet had Elon Musk declare that if Apple and Google removed Twitter from their app stores (something I doubt will happen) that he might make his own phone to compete with them. Generally it's been doom for those that have tried to enter the smartphone market and fight this duopoly.

Thanksgiving is back baby. In 2019 a storm caused lines at some EV chargers. Will it repeat this year, and how do you handle the peak demand for long distance road travel?

As a companion to yesterday's article about why the death of self-driving has been exaggerated here is an article asking what happens if the doomsayers are right, if people can't pull off a usable robcar and robotaxi for a decade more more.

There are lots of easier, more tractable opportunities out there, and I list a number of them.

This past month, especially with the shutdown of Argo.AI, have seen a number of declarations of the death of robocars. Thank to markets and expected consolidation, there definitely is a rough patch, but here's the argument that the field is hardly pining for the fjords and some things are going gangbusters, and not a decade or more away.

Why is a Bitcoin valuable? While almost all concede that shared faith -- or what I would term "Brand" -- is a major component of all currencies, there has been much debate over whether there are more intrinsic values that can keep the currency or token valuable, or get multiplied by brand to even higher value.
