If you read stories that California just put in new regulations that will change all the per-minute chargers and Tesla superchargers, don't worry, the changes are not that big and don't apply to chargers for some time. But it is worth examining how the regulations, such as they are, exhibit 20th century "gasoline thinking" by imagining that the same rules that apply to gas pumps should apply to electric charging stations. See about it in my Forbes site article:
One of the most contentious issues in robocars are the moral issues involved in testing and deploying them. We hope they will prevent many crashes and save many lives, but know that due to imperfection, they also create a risk of causing other crashes, both in deployment, and during deployment. People regularly wonder if they should be out there tested on city streets, or ever deployed. Even with numbers that are perhaps the most overwhelmingly positive from a utilitarian standpoint, we remain uncertain.
Often when you attempt to install an EV charging station in an older home, you find that the old 100 amp service on your panel is not enough, and the electrician may quote a very large price to replace the panel and upgrade the service.
There are ways to avoid paying thousands of dollars by putting in a modestly smaller circuit, and you may find it charges you just fine. Here is a guide to how to get away with less than a 50 amp plug and save many thousands.
I think driving navigation is a great thing, but the UI is all wrong. It needs to work to understand me, to see the routes I have driven with it 100 times, and only tell me when there is something unusual I need to know, not where to turn to get to my house (or telling me "You have arrived at your destination" at my driveway.) The ideal navigation system, on a commute, won't even say a word to me unless there is traffic that means I should not take my standard route. How do we make it smarter?
California is now collecting the 2019 "disengagement reports" for robocars, which always get lots of attention. But in fact, they are measuring the wrong thing -- it is the safety of testing they should measure in the public interest, not the quality of the prototypes -- and they are measuring it wrong, and pushing companies to do things that may be unsafe in order to meet their wrong and useless metric.
I was thinking about all the different variants of battery powered and hybrid cars, and thinking about the BMW i3 REX, which is a medium range PHEV that uses a small, cheap motorcycle engine to drive a generator. I think there might be two new types of semi-hybrid cars with this approach, so I wrote up a summary of all the types, and where the new modes fit it, particularly a plan to make cars with a receiver in which a temporary generator module can be placed.
If the world switches to mostly electric cars, how will they handle the charging on peak travel days like Thanksgiving? I wrote an article on some thoughts for that, and on evacuations as well.

Here are two recent articles on the economics of electric vehicles.
On Nov 1, PG&E, probably the most common power company for electric vehicle owners, raised the cost of their EV off-peak rate by about 25% in exchange for making the off-peak period last longer. Nobody even noticed, even though a 25% rise in gas prices would be a major calamity in the eyes of many. I look into that math and why nobody cared in:
The FCC has finally declared it intends to take 45mhz of the DSRC spectrum and make it unlicenced instead, though they are still leaving 20mhz for C-V2X (Qualcomm's LTE based replacement for DSRC that is mostly similar with 10mhz still to be figured out. Getting rid of DSRC and the silly idea of vehicle to vehicle communications is a good idea, but they should go even further -- and solve the V2V problem far better -- but making it all unlicenced and doing V2V in phones, not cars.
A recently released tiny study from UC Berkeley gave 13 people personal chauffeurs for a week to see how their travel habits changed. They found their car miles going up 85%, but in most cases it was for silly reasons that would not actually happen. Still, miles will go up with robotaxis -- but congestion doesn't have to increase at all.
Daimler's CEO has said they plan to "scale back" and "rightsize" their robotaxi efforts and focus on Trucking. Trucking is a good field for them, but this is a big bet.
Bet right and the company avoids wasting some money on being too early to the self driving game. Bet wrong and there may be no Daimler.

Two articles this week from 3 conferences I attended.
First look at How Cities are Stuck in the "last mile" and other observations from a conferences on cities and new mobility. I examine how scooter companies are working with cities, and how self-driving car tech is mapping cities by keeping the infrastructure dumb.
Lots of folks were forwarding a story about a battery lab at Penn State that has shown a battery that can be recharged in 10 minutes. This is good (and many other labs and companies have demonstrated other ways to do that. But my key reaction is that those who think it's a huge deal are still thinking of electric cars like gasoline cars that you fill up at filing stations. They aren't. With a recent EV, not on a road trip, you charge only at home while you sleep, which takes zero time. Fast charging is not of value there. An article about this can be found in
Elon has tweeted that the price to pay today to get future self-drive features will rise to $7,000 tomorrow. I write some more analysis of this offering and its price in light of this increase. If Tesla really pulls off a full self driving product ahead of everybody else, might it be better to just buy the stock and spend some of the profits on the higher price in the future?
Watching a 3rd party video of a Waymo minivan operating entirely vacant, I was a bit surprised (at 1:05 in the video) when the van did not pause after the video-shooting driver of the other car pulled up next to it by going into the oncoming lane, and then it cut left in front of that car. All very slow and not dangerous, but not what I expected. In the article in comment #1 I link in the video and muse on the issues of handling situations like this.
Tesla released their latest Autopilot safety numbers, and they show a good improvement over the previous quarter.
At the same time, they continue to use strange wording in the report and refuse to answer questions about what their wording means or give the clear statistics that would let us evaluate what the stats really mean.
I get into the numbers in my new article Tesla 3Q numbers are good but still have odd wording
