They’re less flammable than the lithium polymer ones but there is still a risk of thermal runaway where hot toxic gaz can escape and start a fire in the vicinity.

Beware of flaming hazards if it contains lithium battery cells though. I think the main advice from fire fighters is to not keep it close to the only exit out of the room it’s in. And away from flammable materials if possible.

It sounds like a great train system they have in China. Too bad you’ll be barred from buying tickets if you cross too many pedestrian red lights. This doesn’t make the US better, it just shows it’s not black and white.
