Also, I actually had a vehicle from 1987 that totally flooded the cylinders with gasoline due to a fault in the carburetor, and even then it didn't explode when I started it.

Seriously though, what's up with these EV's that'll just as soon randomly burn your garage and house down while you're asleep and the car isn't even running?

Liquid gasoline is not what will explode. You need vapors. Gasoline still requires oxygen to burn, so if air is not mixing with the fuel, nothing's gonna happen.

An internal combustion engine relies on having an environment of maximum flammability in order to function correctly. It's when that environment is no longer contained by the engine that you run into catastrophic problems. Multiplied by how empty your fuel tank is.

This is quite true.

Still, gasoline doesn't have a tendency to up and spontaneously combust all on its own, it takes some sort of external spark or flame to ignite.

Lithium batteries play a different game of Russian Roulette though. The car doesn't even have to be running for one worn out cell to overheat and cause a catastrophic chain reaction blowing the entire battery pack.
