However back in 2016, only about 4% of our cars were EVs[2]. So the 2016 car fire statistics is essentially just ICEs, which would include young ICE cars as well.
In 2022, around 20% of our cars were EVs. Given that the age of our cars has remained roughly the same, if EVs were as likely to catch fire as an average ICE in 2016, you'd expect[3] around 140-145 EV fires in 2022. Yet there were only 29.
Of course, that's assuming I did the math right.
