Gate?

The difference here is that when a gasoline car burns it goes at most
POOF (that's a bit more violent than WOOF). Gasoline cars don't
explode, Hollywood/Bollywood notwithstanding.

A propane or natural gas car goes BOOM and you don't want to be
anywhere in the vicinity. I've seen a video of an old CNG Holden
Commodore is Australia that caught fire... spectacular when the tank
blew.
