It'd be overall vehicle burn rate, including accidents and malfunctions, which seems fair since I doubt you'd give an electric vehicle fire a pass just because it had been in a crash.
It actually seems like a reasonable number. Just some napkin math, ~290 million vehicles in the US / average vehicle life of 20 years * 1.5% burn rate = ~217,500 vehicle fires per year which is very close to the actual number.
I have personally seen several vehicle fires, including an unattended car in a parking lot. I don't even drive that much. I don't know why you'd assume that pumping flammable liquid around at high pressure wouldn't result in a fire from time to time.
1.5% means what? That 1.5% of ICE vehicles spontaneously combust? Is that the number you really want to go with?
