Ever done a mountain run and seen a car go over the edge? I have. Kid's a good driver, just mis-calculated a curve. He was well experienced with that run, too. Don't say you're too good to mess up...

Point is, he went down nose-first. Had to be pulled from the rear. Couldn't pull the front. I could very easily see a car spinning and going down tail first. However, I don't see the bumper cover being your biggest concern, at that point.
