ICE engine fires mostly happen on old, unmaintained cars. Very few almost new $60k++ ICE cars spontaneously combust because of the fuel (a short circuit in the dashboard would cause a fire in any type of car). When they do they're relatively easy to put out. And it's a bit easier to spot a potential fire hazard in advance, providing you do the regular checks. On the other hand a battery fire is about the worst kind of fire a regular person might encounter in day to day life. It's a nightmare even for firefighters. They are very hard to put out and don't want to stay out. There's also no easy way to inspect the battery for such fire-causing potential defects. A single defective cell can cause a thermal runaway event. It's the unpredictability that makes battery fires more dangerous. At this point we have no feasible preventive measures, no yearly service visits, no visual check for leaks, nothing.
