Battery, ICE, Hybrid: What About Temporary Mixes?

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.

Can An Electric Car World Handle Thanksgiving Travel?

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.

EV Electric cost goes up 25%, nobody blinks, plus why your Uber isn't electric

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:

FCC starts to take the DSRC spectrum back for unlicenced

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.

Traffic doesn't go up 85%, and we can solve congestion

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 Makes Risky Bet Pulling Back From Robotaxi Business

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.

Cities stuck in last mile, Stupid Cities, Scooters and the future of Hydrogen

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.

Recharging in 10 minutes is less exciting than you think

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

Tesla "full" self-driving will jump to $7,000 tomorrow

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?

Waymo unmanned vehicle has debatable encounter with erratic videographer

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 3Q numbers are good but still have odd wording

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

Tesla smart summon is a self-inflicted wound

I tried out smart summon on my Tesla yesterday. Both times it got confused and stuck for so long it blocked parking lot traffic and I had to run into it to move it. Videos have surfaced of the cars (gently) hitting things. Even if there it's working well for many people, these results erode confidence in the capability of Tesla's systems. Tesla has driven over its own foot releasing this product in this state, and for nothing, since it's not at all useful.

Uber drivers as employees, competing with robotaxis

With a new California law threatening to classify Uber drivers as employees, I examine if a law like that could really work or Uber can get around it, and also what happens if this makes drivers cost more -- and leads them to a tougher battle against their real competitor, the robotaxi.

Falling asleep with Autopilot on -- does it explain Tesla's numbers?

If you fall asleep while driving with Autopilot, it's not a good idea, but you're much safer than falling asleep in a car that doesn't have it. Since a lot of accidents are caused by falling asleep, could this be the reason for Tesla's claim that driving with Autopilot is much safer than not? Or is that claim itself even valid? I outline the logic and math in my new Forbes site article at:

Tesla battery guru and new super-lifetime cell

Tesla's "battery guru" from Halifax, NS released a paper on some new battery cells they have been testing in his lab and getting 6,000 cycles from 0 to 100% on. That's a lot better than today's cells which offer 2000 cycles from 20% to 80% if you are lucky. This could be very big for electric cars, grid storage and it is suggested even robotaxis -- but their needs turn out to be more straightforward than originally thought. But it does bring down the cost.

NTSB lets us look inside a new Tesla accident, what does it tell us?

Because Tesla Autopilot is driving tons of miles it's having accidents, and the NTSB in investigating them. That gives us a window we would not have into what's happening. The NTSB report on a non-injury Autopilot accident came out recently, and let's just learn what Tesla's autopilot didn't perceive.
