I can keep you updated on my own EV ownership if you'd like. I bought a '22 Chevy Bolt brand new for $27k a hair over 12 months ago and so far it's got 51,000 miles on the odometer and the battery has lost only 10 miles of range compared to the 240 it came with, which is such a small loss it might actually be due to the wind or temps on my test since I do my range tests on the freeway during road trips. Despite driving on average more than 137 miles every single day in this EV during the summer, rain, winter, and multiple snow storms (yay Midwest -_-), the battery seems to be holding up pretty well. My plan is to drive the car for at least 5 years before considering a replacement, at which point I should have between 230-270k on the odometer. The only maintenance items on the car are tires every 50-60k, new coolant in the coolant loops every 150k, brakes every 100k or whenever they wear out (which varies wildly based on how an EV is driven), and wipers + wiper fluid as needed.

My goal here isn't to put you on blast or call you a liar because skepticism is fair. I'm just sharing my own experience so far with a car that runs on EV tech last updated in 2015. I was pretty worried the "abuse" I'd be putting it through with my driving would cause it to have problems or perform worse than it should, but so far it's doing great and the battery isn't any worse for wear than other Bolts who have published their numbers online.

Personally I'm really looking forward to finding out how well the 2022+ Tesla Model 3s do with the new LFP battery because supposedly they'll be a big improvement over the NCM batteries they have been using (which my car also uses) when it comes to longevity and being left alone for really long periods of time (months, years).
