BTW, is it true that at Tesla's Supercharge stations, you pull into the service bay, a machine disconnects your discharged battery, moves it out from under your car, and brings in a fully-charged one and clamps it on, all in a few minutes?

Tesla is a Technology company first and a vehicle manufacturer second. Trying to build infrastructure to charge the ones now made, failing in even coming close to build what has been ordered, and still coming out with new models. Going straight to being a victim of its own success, or lack of it. I guess aiming high, you can still shoot yourself in the foot!
I have never even seen a Tesla on the road. The nearest charging station is about 50 miles away in a mall parking lot, but I can't say I ever even noticed it was there until I looked it up one day.
Venture down to a wealthy area of Florida and you will see a Tesla at every stoplight.....
I know the market outside the west coast is small for electric cars. Do you think it would pay for a gas station with a built in restaurant/sitting area to install a charging station away from the gas pumps? I’m thinking gas stations just off the interstate highways could be a test bed for such a program. It could be set up like how some stations have a separate coin operated air pump. They could set it up to use a credit/debit card payment. Pull into the station, plug in the car, swipe the card, go inside for a meal, and come back out to head back on the highway.
I’ve seen stations with these in my area (maybe 10-15%) and while traveling. It would be very smart, because the station makes more money on the big gulp and twinkies you buy than your whole tank of gas usually.

While it will certainly be a long time before no fossil fuels are used for power (since we screwed the pooch with nuclear and something needs to pick up the base load when wind and solar can’t), the main idea is that pollution can be better controlled in an industrial process at a few points rather than millions of points at each car. Plus, as power generation shifts away from coal, as it has been doing for at least 10 years due to market forces and will continue to do, as well as additional wind, solar and other power sources come on line, the existing cars become cleaner automatically without any individual driver having to do a thing.

They killed it due to lack of demand.
The battery is the most expensive part of the car. To lengthen it’s life you charge it to 80% rather than 100%. But all that goes out the window when you let a robot take your pampered 6 month old battery with a couple dozen discharge cycles, and slap the other guy’s 3 year old battery charged to 100% on a couple thousand discharge cycles. Your old battery had a 270 mile range and the new one can barely reach 240.
Like most things EV related, the concept is better than reality.
Wealthy folks in the panhandle don't buy Teslas, they buy BMWs and $70k trucks and SUVs.
Wealthy people everywhere buy BMWs and $70k trucks and SUVs. People who notice Tesla’s at every stoplight are doing so because they’re looking for them while being completely oblivious to the hundreds of $70k SUVs they didn’t notice because they’re used to seeing them.
It’s largely psychological, but when I’m interested in a specific car, it seems like I see it everywhere. When my interest shifts to something else, it seems like I see it everywhere.

This is true. Teslas with the largest available battery, cost nearly twice as much as the same car with the smallest available battery.

Umm, no. To lengthen its life, you always charge it to 100%. This must be done carefully, since lithium-ion batteries can get VERY unhappy if you overcharge them, or fail to follow the correct voltage/current regimen when charging. But all the Tesla chargers do follow that regimen, and are carefully designed to never overcharge.
And once you charge to 100%, you then drive the car and discharge it to only 50%, no lower. The less you discharge your battery before recharging, the more charge/discharge cycles it can have.
Don't drive your Tesla until it won't go any more (deeply discharged), and only then charge it. Instead, charge it every night, even if you only made a few short trips and only discharged it down to 80% or so.
If you go on a long trip and discharge it down to 25% or lower, then yes, your battery will get old faster. Try not to do this. Electric cars still have this failing, one that gasoline cars don't have.
But it's the level you DIScharge it to, that costs it more life. Not the level you charge it to, that should always be 100%. If you regularly discharge it down to 25% of its capacity or lower, it will have far fewer charge-discharge cycles than if you mostly charge it when it gets down to 75%-80%,
BTW, if you recharge it fast, the battery will heat up as you charge it, and that heat is also rough on the battery.
The best way to treat an electric car with Lithium batteries, is to charge the battery frequently and slowly (like overnight), even when it's only slightly discharged, and don't discharge it deeply before recharging.
If you only charge it to 80%, then a medium-length trip can bring the battery down closer to the deep-discharge level (bad for the battery) than the same trip after a 100% charge.

Not according to this guy: https://www.google.com/amp/s/electre...-charging/amp/
At 5% degradation at 50k miles makes you wonder what to expect from a semi truck after 1,000,000 miles. Plus the full discharge cycles.
But we’re in the same page. Some batteries are beat up more than others just like some engines are beat up more than others.
