The problem isn't spontaneous combustion, it's having an accident where the battery is damaged, causing runaway combustion.
No one burned to death inside a Tesla while driving normally. It's always following a crash.
I'd imagine if tesla stared to burn they wouldn't "drive normally"...
Unlike in traditional vehicles, most EVs have such a robust firewall between the battery and the passenger compartments you literally have 1+ minute to get out, compared to often seconds in a traditional vehicle.
And I've been following Polish firefighters reports about EV fires and they are very interesting - basically saying that in all recent cases of EV fires they were contained so quickly even the interior was largely undamaged - something that practically never happens with regular cars. Some of these have been in underground garages too, with difficulty of access - but nowadays they just know how to approach an EV fire and containment isn't a problem.
That's a new one. How common are fires after accidents, and what fraction of those burn the car up while someone is trapped inside? I know people occasionally die in regular gasoline vehicles in this exact situation, so is it statistically a higher risk in EVs?
