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:


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 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.


How to pick which range of Tesla or other EV to buy

A big question for most EV buyers is how much range they need. It depends on your commute, your driving area and how much you want to take long road trips, and where you want to take them, but most people will be pretty happy with the 200-250 mile range cars that are starting to come out. But do you want to pay extra for more than 300 miles of range and get that long range Tesla?

Here's an article where I outline how to make that decision:


A solar panel on an electric car is probably false green

Hyundai has put a solar panel on an electric car. Turns out that's "false green" and may end up using a lot of the solar energy to cool down the car after you park it in the sun. What do the economics on solar panels in cars look like?

See Hyundai puts a solar panel on an EV but it's probably false green


Tesla Autopilot alleged failure makes you wonder about how they train it

Another Tesla car crash, allegedly on autopilot, teaches us something about how well (or not well) Tesla is doing with its claimed ability to use its fleet of cars to quickly learn to identify unusual obstacles and situations. Here, a Tesla on autopilot crashes into a tow truck sticking out into the right lane (injuring the Tesla driver.) The driver says it was on Autopilot but that he was distracted for a few seconds.


Tesla and NHTSA fight over what safety scores mean

Tesla advertised that the Model 3 is the safest car ever based on NHTSA's tests. NHTSA wrote them a letter saying, "stop saying that, you can't compare these scores across different weight classes."

Here's some analysis of who is right and why Tesla wins in the end at NHTSA and Tesla spar over safety claims


How RV Parks can exploit a new market of EV road trippers

RV parks already have the infrastructure for charging electric vehicles on road trips. They just need somewhere decent for the road trippers to sleep and they can exploit a whole new market. Some already rent little cabins. If they add glamping tents they can serve customers at a low cost and could quickly fill out the many gaps in the EV trip network. In my new Forbes site article, I outline the things they could do, and give some advice to drivers too.


How to not waste most of the public EV charging infrastructure

Over 60,000 EV charging stations have been installed in the US. But a huge number of them see fairly light use because they are not in the right place for the current generation of electric cars, and not for the coming self-driving ones.


Make Supercharging better by ordering food in advance

Outlet malls are common supercharging sites, and they do not have fine dining.

I've written about how to make Tesla Supercharging work, you try to have a meal while doing that. Here's a proposal to make that work much better: Be able to order food from participating restaurants while on the way to the charger, and have it all timed perfectly to either:


If you buy land that will be covered by rising seas, should the government help you?

In Venice, Acqua Alta rising seas flood the streets many times each year. They plan expensive inflatable dams.

Evidence mounts that sea level rise can't be avoided now, absent some miracle of geoengineering, and maybe not even with that. Even if you're one of those who insists human pollution isn't the cause, the planet is getting warmer, the ice sheets are melting at extreme rates.

Would a rental battery pack be a better choice than a super-long-range electric car?

When you buy an electric car, you can often choose among various battery sizes. The larger your battery, the more range you have -- and you may get some extra performance -- and the longer your pack lasts, but the extra capacity is very expensive and adds weight to the car. The truth is, most people only need the extra capacity of a long range car when doing road trips. A modest 150 to 200 mile range car is sufficient for driving around a town, depending on the town.

Teslas keep changing prices and frustrating buyers

What price are you today?

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.


Tales of an Electric Car Road Trip and Supercharging strategy

I digitally removed a score of instagrammers trampling these lovely flowers.

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.
