@p @ForbiddenDreamer @catmanmancat @A39IsTOZ8SJIr2oM2y.graf@poa.st The car will still win - LPG tanks are massively overbuilt - a bike tire in mild temperatures could keep LPG liquified.

A car striking such a tank will in 99% of cases will just dent the tank - there would need to be a really unlucky situation where the tank is split right open, the LPG given several seconds to form a cloud of the right ratio (too long and the cloud this) and then an ignition source applied at the exact time for an explosion to occur.
