I looked at this awhile ago. There is a google doc maintained by some anti-Tesla investors who track every fire that can find. It is still much lower than the US average fires per car.
I think it gets more attention because:
- some people are financially incentivized and;
- battery fires really are a much worse deal than a normal car fire
The advice I’ve been given (on train/bus batteries) is to shove the vehicle if safe when it starts; then do whatever possible to fully submerge in fresh water. Obviously that isn’t really feasible.
I think the issue might be visibility.
Naively, it feels like most of the issue is from a small number of extra sooty vehicles. But that belief is probably just because of how visible it is. The brake/Tyree dust isn’t visible because it is more spread out.
