I was three or four years old (late 1980s) and had been left unattended with the television. Something was on, probably from within the last ten to fifteen years, so think 1970+. The language was in English, American accent, I believe.
At one point, a person I believe to have been the badguy, in a green camo flameproof suit, was spraying massive flames from a flamethrower at a small house or shack. The good guy (I think it was) got out, and got into his car or truck. Time to drive away!
Except the engine wouldn't start. On one side of the car, a mechanical flag (I was young; this is what it registered as) went up, with some sort of taunt or warning. Then one showed up on the other side. After that, the radio display turned into a time bomb countdown. Our hero tries the door handles, which are now inoperative. He's trapped! Eventually he kicks out a window of the vehicle and runs away before it blows up.
I've wondered if this were an episode of MacGyver, some Arnold Schwarzenegger film, even a James Bond film.
