Not only that, but burning aggressively. I've seen my share of car fires, having worked in EMS for 12 years, there's no such thing as a gentle car fire; if they burned any more aggressively, they'd basically just explode. Well, something about the lithium makes these fires fucking rip and they're a nightmare to put out. I just did some quick googling, and supposedly Li-ion battery fires are able to supply their own oxygen (holy shit), so you can't put a lithium battery fire out by smothering it with water or foam. Maybe I'm wrong and someone who isn't an Internet idiot (it's me, I'm the idiot) can correct me, but that sounds hella bad, and like of one of those cars caught fire in that tunnel, that fire just flat out isn't getting put out.

That's fine. That thing is halfway round the globe. I'll be just fine
