1 ton of Lithium is enough for ~100 BEVs which will each displace >4,000 gallons of oil. That's ~400,000 gallons of oil. Last I heard here in TX/NM we need ~50 gallons of frack water to extract 1 gallon of oil. So we can use 20,000,000 gallons of water for ICE or ~500,000 gallons of water for EVs.... and we should get that lithium back at EOL... whenever that is.

Material shortages are overblown. Proven reserves of key materials are higher today than they were 20 years ago because we're still finding them faster than they're being mined.
Water also doesn't just vanish into nothing when it is used as a part of some process. If the process involves removing lithium salts from seawater, the water is still water after the salts have been removed (and the compounds that you are not interested in can be put back in - sodium chloride, for example).

I had a 2016 for three years in all year round desert heat (south of Palm desert area) and didn't notice any degradation by the time I returned it. Maybe a month or two of sub 50 degree weather but the rest of the year temperatures ranged between 80-110.

Or, you can package the sodium chloride and sell it for high dollars as a "designer" salt.

Good to know, thanks for the feedback. VW did change battery vendors in 2017 and went with higher capacity cells (I think in the same overall space). Hope the current cells are as good as the old ones.

Default EV's are as sustainable as computers and smart phones?

I’m forever reading about cars and a concept came up of interest: The decision to repair or replace a car should not be only what the car is worth compared to the repair cost. It’s better to base the decision partly on what it costs to replace the car, as you are probably aware by now, especially expensive EV's. This is why I value really nice cars which rarely go below, say, $5000 in resale value and are usually worth putting in a $2,000 repair if they satisfy my needs and desires. If you keep your car up to “new car” standards, it might actually be worth $3000 or maybe more. But the car needs to be useful to me so breaking down every few months or worse, having skimpy repair support (read: Tesla) is a reason for me to replace it with a new one that I can pamper and keep “like new” for a longer time. See: https://www.ericpetersautos.com/2019...ty-considered/

Tesla's dodgy parts availability and repairability in general is not an EV problem - it's a Tesla problem.

There are people who drive fairly decent $1500 cars and when something major goes out they buy another fairly decent $1500 car. I did this for years when I was young. Get used to whatever is available though and usually old dead peoples cars. I have bought many decent low priced cars from family estates.

We also have the issue down here where there are those who buy an inexpensive car that has a relatively fresh registration on it then never registers it or insures it then sells it again before the registration expires. Then buys another one of the same as described.

Part of the issue of whether to fix or not is not having a trustworthy mechanic known to you. Most would rather buy new than chance spending big money on a repair they can't have confidence that the job was done correctly. One of the reasons I sold my 2003 Beetle that I had runonbeer do lots of work on. When he moved away it was better for me to buy the stop sale 2015 Beetle with the long warranty than try and deal with unknown mechanics to get any work done on it.
