The most dangerous game/sport?

Nicky Hayden's death is really bumming me out. I'm not really into MotoGP, but I knew he was, had seen him on occasion. Maybe it's because I follow NASCAR and cycling; all the top guys in those sports have been commenting on Hayden's death. There's a lot of crossover fans and relationships, I guess. It's strangely sad seeing Peter Sagan and Chris Froome torn up by the same thing as Jeff Gordon and Jimmie Johnson.
