This should answer your question.
I love that M3 crash video!
That sucks that it happened, but he most likely never took an advanced driving course as his skills just displayed.. (not being on throttle while cornering, not braking before going over a crest that you have no idea whats on the other side. his steering inputs were ridiculously sharp and not smooth, good way to upset the chassis.) I'm no pro, but i don't do dumb **** like that in an $80k car.
