Put a thirty thousand dollar car into a tree on an icy winter road... This was an accident.
Wadded up a couplethreefour motorcycles, as well. But since the 'victims' were rescued from junkyards for the express purpose of being hammered to death on a racetrack, I should think that doesn't count.
For an example of what happens, feel free to YouTube the word "Highside". The results are entertaining.
