Worst car accident you've ever been into?

Mother backed into a guidewire and put a little crack in the back of the car.

When I was little my mother would drive me to this day-care thing every day on her way to work, but one day I was sick and stayed home with someone, and she got in a bad wreck, the whole passager side of the car was caved in, and if I was in the car with her that day I'd probably be dead.
