I wouldn't get that to daily drive however cheap it is now, it will be branded fire damaged on the title and not be able to be registered here 🤣
But yeah the story might be more to do with the door handles, I think it ripped out the underside of the car as it went through the shallow ditch and bank, which appears to have some rocks on it, one of which a rescuer grabbed. Then the fence post that went under may have impaled something. So I wouldn't bet against a gas powered car having it's gas tank ripped open in same situation. But then something needs to ignite it, and given the car seems to be driven recklessly, that might have been hot exhaust/cat or brakes, though depending how it got ripped up, there was wiring that could have been ripped out and arcing, fuel pump supply is fairly high amp. Safest car to have been in for that one would have been a diesel.
Whatever you are rolling in, this shows the benefit of thinking about an escape plan before you need it, a convenient stranger with rock is super lucky. Electric door handles aside, there's ways you can get trapped, due to impact on the sides, or being stuck up against something. There exist some emergency escape hammers you can keep in glovebox or console. If nothing else available, maybe have to try holding the seatbelt buckle between your knuckles, to punch with, or kick out the front or rear screens. If you have electric handles with no mechanical connection, try to think to drag the seatbelt out with you to stop the door closing again in this sort of scenario where you can get out once before the body electrics fail.
Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.
