> A car, especially an electric car, with that many miles is likely over half way through it's lifespan and it's in the most maintenance heavy half to boot.

Teslas have shown to last hundreds of thousands of miles. I'm unsure how you've come to the conclusion that one with 80k miles is beyond 50% of it's useful life.

Even Nissan's CEO has said Leafs are lasting longer than expected, and their battery management (air cooled) is garbage.

Were those Teslas used as rental cars? Were they charged/discharged aggressively by users unconcerned with longevity?

I rented a Model Y from Hertz. The battery life was suspiciously poor during the 3 or so days I drove it, necessitating multiple trips to a supercharger.

Don't underestimate the abuse from rental customers.

It's a battery and electric motor(s), it doesn't matter if they were primarily fast DC charged and the users beat them up. I have beat the shit out of a 2018 Model S for 110k miles and I've only had to put tires and wiper fluid into it. I have primarily Supercharged it back and forth across the US more times than I can count, and I've only lost ~7% of the 100kw pack range.

> We compared cars that fast charge at least 90% of the time to cars that fast charge less than 10% of the time. In other words, people who almost exclusively fast charge their car and people who very rarely fast charge. The results show no statistically significant difference in range degradation between Teslas that fast charge more than 90% of the time and those that fast charge less than 10% of the time.

The suspention system is the same wear. Where I live salt is what gets cars not miles.
Not an EV specific problem. Have a mechanic inspect the vehicle’s mechanicals prior to purchase if you’re risk adverse.
that is the point. the significant wear on a modern car is things that are common. ICEs last a lot longer than the rest of the car these days.
I bought a gas car from the last hertz liquidation sale and it’s been great.

I don’t think people abuse rentals as badly as you may think. Even the aggressive charging has only been happening for what, a year? It’s not going to cut the life all that much imo.

I thought they determined supercharging doesn't cause appreciable degradation.

Gas cars last hundreds of thousands of miles too. I still expect a big discount on them.
The ones which actually last, i.e. toyota/lexus products, have the associated "toyota tax" for their used vehicles. No good discounts going anymore except on dying out sedans
It’s not really a brand thing. I’ve never owned a car for less than 200k miles, and a couple for substantially more. Do the maintenance and they last.
Most cars last 200,000 miles with maintenance.
Yeah maybe I'm underestimating them in that case. Every other battery powered device I own degrades a lot faster than that but I guess car batteries are higher quality.
