Call me chicken, but the first thing I'll pull if my car is afire is a quick exit, stage left.
A man's got to know his limitations and I'm no Jim Kelly.
I do have a buttload of stated value insurance. What I don't have is interest in carrying a 10lb fire extinguisher, heavy gloves and the hope that I can crack the lid in time while dodging flaming, dripping polystyrene.
Let it burn if it's time, just keep me and my passenger safe. I can buy another one (car, that is).
