Indeed. But, the fire doesn't spread the same way it does when a diesel fuel tank melts.
The end result would probably be very similar if left to run for say 24 hours.
Realistically however it wouldn't be.
ICE is more likely to get out of control if not dealt with really really quickly.
Once one goes up as soon as that cars fuel tank is breached then with how closely cars are parked its almost guaranteed to take another couple out within minutes. Rinse repeat.
