I used to have an '88 Olds Cutlass Calais, basically a four door rollerskate. I was in the back hills of southern Indiana in July of '99 and I encountered about a 40 degree downgrade, with a hairpin turn at the bottom. When I entered the turn, I hit a patch of gravel and went straight sideways into an eight foot deep ditch at about 35 miles per hour. The car was completely totaled, yet I was completely unharmed.
