I saw a Volkswagon beetle explode once. It popped out the windows, apparently a battery charger was left on the high setting and overcharged the battery thus filling up the interior with excess hydrogen gas, a mechanic started the car and a spark detonated it, the poor guy was working on the car at a shop years ago where I also worked, he was unhurt except for some ears ringing.
The battery is exposed and under the back seat on older Beetles.
In high School, one Halloween guy was drive bying us and chunking cherry bombs (yeah the real ones) at us out the passenger window, well one hit door, bounced in backseat, he bails out, runs along side bug, then “whump”, hops back in on the run and hauls butt,,,, LOL
