There have been ten different prices changes to Tesla Model 3s since I got mine just over 4 months ago. While one expects electric computerized vehicles to go down in price over time, most buyers didn't count on anything like this, and people who rushed out to buy "before the price goes up" are not happy.

Tesla side-announced that people who lease a new Tesla won't be able to buy it at the end of the lease like you normally can. Instead, Tesla will put it into robotaxi service (presuming they are ready to do that in 3 years.)

I'm back from another electric car road trip -- more later on that -- but here's a story where I provide a report from a Waymo One user on how he sold one of his family's two cars and replaced it with robotaxi service. He's an early adopter, but he helps us examine just what some of the issues are around getting people to do that.

I recently purchased an LG 4K OLED HDR TV. In spite of the high price, I am pleased with it, and it's made old HDTV look somewhat dull. There is now enough content to upgrade.

Read my review and also my comments on how the TV hasn't yet figured out that many of us just want it for streaming.

Yesterday, I detailed issues with using superchargers on a Tesla roadtrip.

This month we took an electric car road trip in the California desert to see the flowers. The idea of a road trip in the desert with an electric car would have been crazy not too long ago. Now it's becoming possible, soon it will be easy, but there's still lots to learn.

There are over 100 companies out there developing small VTOL "flying cars." And they're all making different decisions on several important design choices. I've written a breakdown of the key design decisions and what they mean, which forms a sort of taxonomy.

At Nvidia GTC, the giant European testing lab AVL presented their plan for certifying robocar safety the European way. It is both too much bureaucracy and too little testing and won't work.

This week I am at the Nvidia GPU Technology Conference, which has become a significant conference for machine learning, robots and robocars.

Here is my writeup on a couple of significant announcements from Nvidia -- a new simulation platform and a "safety force field" minder for robocar software, along with radar localization and Volvo parking projects.

Earlier, I wrote about what happens when we put renewables on the grid and how complex it is.

Yesterday, it was announced the state attorney in Arizona will not press criminal charges against Uber around the fatality a year ago in Tempe. It is still not decided if charges will apply to the safety driver.

I have a Forbes.com piece on the nature of fault in the Uber crash:

Readers all know I love robocars and write about the tremendous effect they will have on our lives and cities. But a new technology, running about a decade behind but now real, is coming which could have even more dramatic effects, the e-VTOL or "flying car."

Of course, just after releasing my review of Tesla Autopilot they announced new pricing and features, with some explanation of what "full self drive" is.

For now, it turns out it's still driver assist, but on city streets. It's an interesting question if that's a good idea. I offer some additional analysis and updates.

We all love open source. But the usual rules of open source break down if every vehicle deployed on the road has to have gone through a complex and expensive safety certification process. You can't just download, patch and go.

So we need other solutions to allow the world of the tinkerer/hacker and the innovation and superior function it can provide.

Since the famous Trolley Problem has come up again recently thanks to the MIT Moral Machine, it's time for what seems to be an annual debunking of the notion.

This time, to illustrate the pithy headline above, I tell the story of why the hypothetical situation is even rarer than people imagine because of the way braking and steering systems are designed on robocars, and how their driving patterns will be designed to minimize risk.

For years, the most common slide in a skeptical talk on robocars would show a cop directing traffic, and ask how the cars will ever handle that.

Here's a video from Waymo showing off that ability.

I have written often about the new economies in transportation that future technology like robocars provide. In my research I've learned something that seems to not be well known in the transportation world -- that often, smaller is better and more energy efficient.
