Gasoline fuel tanks can explode. Google it.
"Images of cars exploding on Google?"
Google it. It's a thing.
"Adamantium?"
This is called making a point through absurdity. Fuel tanks are made of steel or plastic. Neither of those is unbreakable.
"Whatever, just keep repeating this sort of stuff and maybe some more people will believe you."
Maybe. I do have the full backing of the Conspiracy of Lizard Peop---

They do, but it's extremely rare (thanks to modern inventions like pressure relief valves). When a fuel tank explodes, it's not because the fuel inside detonates, it's because the fuel inside is being vaporized by the heat of the external fire, and that vapor takes up a whole lot more space, resulting in a huge pressure increase, resulting in a BLEVE. If a pressure release valve can vent the pressure before that happens, no explosion...

That being said... I doubt there was actually an explosion. The car simply caught fire. There were certainly pops and bangs as various compressed gas cylinders (for things like air bags, doors, bumpers, seatbelts, etc) BELEVE'd, but I seriously doubt there was any major explosion. The 'bomb' sounds were simply the crash itself.
Always approach from a corner, sweep the hose stream under the vehicle to push out any burning fluids, then flood the interior with as much water as you have.
There are so many things in a car that will try to hurt you... Those little hydraulic cylinders that prop up your rear hatch? When those heat up enough to cook off, they'll drive that rod through your leg... The compressed gas cylinders that give the bumpers their 'bumpiness' will kick the bumper out hard enough to break a knee... Hopefully the fire hasn't gotten hot enough to ignite the magnesium that is in a lot of modern vehicles... And here's hoping electric car manufacturers really know their stuff... A lithium fire doesn't sound like fun at all.
