For my EV, which I charge about once a week on average, with 4,000 cycles that means about 77 years!! That's a huge deal. CATL quoted 10k cycle battery too. Wow. Very cool. Yeah energy density and operating profile and all that. But color me impressed.

It’s not only about longevity in time but also in terms of miles.

For heavy users and given a standard range of 250+ miles, we are talking about a longevity of 1 000 000 miles. I never had a car with more than 200.000km (120 000 miles).

In the US you see a lot of cars with many miles on them because distances are bigger there, especially on the west coast.

Also, there's just smog you need to pass which is significantly less than in many other developed countries. Some have yearly required checks that would check all safety features like brakes, tires etcetera. That's where a lot of cars fail that would just keep driving in the US

A lot of states have yearly inspections.

Outside of the rust belt, cars last quite awhile as long as you change oil and the occasional rubbery bit.

I'm actually scrapping a 99 Jeep TJ right now because the OEM powertrain is just awful, but the rest of the vehicle is perfectly fine.
