Actually, gas tanks usually only explode in the movies (not always, but in most cases). I'm a certified fire investigator and engineer, and a gas tank with gas in it is above the upper explosive limit (UEL), as there is not enough oxygen in the tank to get to the right mixture. It's when the heat from the fire causes the tank seams to split is when it becomes an issue, and it's usually not an explosion but a huge flame-up due to the new combustible fuel adding to the fire.
Propane, OTOH, is a way different beast....

Yep...what he said. I've been fighting and investigating fires for the past 30+ years, and of all the vehicle fires I've been to, I've never seen a gasoline tank explode. The driveshaft..well, that's another story. That sucker will put shrapnel in your shins if you ain't careful. And those new-fangled bumpers with the shock-absorbers built-in.....yeah, they'll explode too.
