The fuel tank is usually located at the back not the front & generally survives intact in a frontal collision & there are shut-off valves in the fuel lines to the engine so that fuel doesn't leak everywhere in an accident. The system isn't perfect, but I suspect that in this particular incident had the vehicle been a modern petrol fuelled one there would have been no fuel leak. Look at the Tesla in that video - the rear of the car is pretty much intact.
