Replacing the batteries with new ones on my $50k when it was new car (BMW i3) would cost me about $10k. Which is roughly what the car is worth on the second-hand market right now. The chances of me ever having to replace said batteries are basically zero. The chance of an ICE car spontaneously setting itself on fire are actually much higher, so this is a massive nothing-burger. When owning a car you should ALWAYS think about what happens if said car is suddenly total-loss the next day. Usually the answer is to replace it with another second-hand, not buy a new (!) battery from the dealer. Hell, second-hand battery packs are a thing too now, and much cheaper. On most EV’s you just drop them from the bottom and pop in the replacement, much less work than replacing an ICE engine.
