I was watching an MSA video last night and motorsport as a whole isn't even in the top four most dangerous sports. Bear in mind that on a half marathon in England the other year 4 people died, that doesn't happen in rallying but you don't hear people crying on about the dangers of running. It's just not fair.
For the record check out Group B on Youtube to see how dangerous it was. The cars were nuts compared to the well designed WRC cars of today
