Looks pretty cut-and-dry in that vid and from those pictures. Sad deal...hopefully it doesn't spell the end of the races, otherwise I'll have to set a different life goal.

If any obvious changes need to be made in the name of safety, by all means, but don't eliminate the races. Spectating at any event with fast moving machines is inherently dangerous. Maybe I'm weird, but whenever I'm at an auto race, air show, rally, etc., I always stay in the vicinity of cover, or at least pay attention to where trajectories will carry things. As this accident shows, you can always be SOL, but the understanding should be there. I guess as a "pilot" and racer (cars), I've seen enough to understand it's not as exact a science as people want to believe. The question is not if it (or you) will fail, but rather when. The worst are rally fans, I swear they have a death wish. Not that I necessarily have a problem with it, but there is this term lost in today's litigation happy society and that's "at your own risk."
Regarding insane rally fans, imagine what would happen if this driver got it wrong. More than a few times Grp. B rally cars came back with digits stuck in the wings and fatal crashes (some involving spectators) were eventually what killed the class.
