This actually is on behalf of my wife. She has a morbid fear of dying in a car wreck(as opposed to dying in a nuclear holocaust, go figure). She can't identify the source of her fear in that she's never been in any kind of a car wreck. As I am usually the chauffer when we're out and about, I have to be pretty conservative in my driving (speed, following distance, going for those yellow lights) or my wife will literally push a hole in the floorboard, hitting her imaginary brake pedal over there in the passenger seat. If it weren't for the fact that she really panics at times, it would be comical...well OK sometime its comical anyway.
