And this post from a forum in 2017 and the reference is to Richard Hammond super car crash after Swiss hill climb challenge where battery kept reigniting over a 3 day period.
'Firefighter here. I attended a Tesla training in which they actually rolled over one of their $100,000+ cars and showed us what's what. They build in battery and electrical disconnect points for us to use during the extrication (read: destruction) process, but when a car is as badly damaged as Hammond's, they may not be accessible. The best bet is to enter a defensive mode, let it burn and just focus on keeping the fire from spreading to exposures (vegetation, structures, etc.). This is one of the many aspects of modernity that's making us rethink the "smash and spray" mentality of the past. I wouldn't say we hate electric cars because a good fireman likes a good challenge, but the amount of resources and time they consume (5 days?!?) make them expensive. If you want to talk about scary for firefighters, let's talk hydrogen fuel cells...'
So the question is how man tow trucks would be happy to remove an EV with badly damaged battery pack which had caught fire from the accident site...
