[cbzzokyh] Hydrogen car explosion

A car encounters damage and, in accordance with the Hollywood trope, explodes in a giant fireball, seemingly unrealistically.  However, this car has been established to run on hydrogen, perhaps liquid hydrogen and hydrogen fuel cell.

Gasoline only has a very narrow range of vapor concentration at which it is explosive.  In contrast, hydrogen explodes in air over a very wide range of concentrations, so the Hollywood trope becomes possible, even likely.
