I mean when it burns it burns, it's a total either way, it just blocks traffic longer than a normal car, with the upside of not leaking burnable liquids that can do damage in larger areas.
Car fires from ICE's are magnitudes more common and cause more damage every year because of this. If you spent half a second to search this you'd find that reports indicate that per 100,000 vehicles sold in their respective powertrains in their lifetime, 25 electric cars catch fire, and 1,530 gas vehicles catch fire. While searching this, something that caught me off guard and surprised me was that hybrids are even higher, 3,475! The more you know.
