IIRC replacement Tesla batteries can cost as much as $20,000 USD. I've heard of some making close to half a million on the original battery, while others fail just past 100k. $20k is a bit of a rich gamble for me personally.
Insurance would be interesting on a Tesla. On one hand it could be less because of all the "safety tech" they have, while on the other hand new EV bodywork is crazy expensive (see
this $42,000 repair from a minor fender bender on a Rivian) which may prompt insurance companies to raise rates on similar vehicles.
