"Data from the National Transportation Safety Board showed that EVs were involved in approximately 25 fires for every 100,000 sold. Comparatively, approximately 1,530 gasoline-powered vehicles and 3,475 hybrid vehicles were involved in fires for every 100,000 sold."

That's 1.5% chance of an ICE car burning down, 3.5% of a hybrid. That's even higher than I thought.

I assume this is including accidents and they probably account for the majority of fires, but ICE cars also catch fire parked sometimes. Off top of head, there was a Mercedes GLS recall and the recent Kia Telluride/Hyundai Palisade recall due to car fires in drive-ways/garages when parked.
