While no doubt you were speaking colloquially, I'll point out that the nature of a warhead explosion as compared to the breach of vehicle fuel tanks (even violent ones) are different.
A warhead detonates, and is the resulting pressure wave that causes the vast majority of the destruction. A breached automotive tank typically deflagrates which, while dangerous, is not on the same level as a "warhead".
The typical exceptions would be pressurized fuel tanks like propane or H2, which would typically "BLEVE"[1], which is also a different type of detonation.

While a BLEVE is a (terrible) thing, that does not prevent leaking, non-pressurized fuel from a vehicle to vaporize and mix with air, forming a mixture that can ignite accidentally in much the same manner as it happens (by design) in a thermobaric weapon (a.k.a. FAE, Fuel Air Explosive).
In fact, the risk of having a sudden ignition of a significant volume of vaporized fuel / air mix seems worse in a burning ICE extraction scenario than one involving a BEV, where a fire can be expected to evolve in a more gradual manner.
