Well I do enjoy some motorsports, so I realize that some people just don't get "it" for certain things. But I would think in that case, since there is no clock or whatever to compete against, the "winner" would be based on crowd response. So, be the last guy in the contest, when everyone is totally trashed and has about a 5 second memory, and you will win. See, easy! I like watching a good rally driver, but I never got the competitiveness of drifting for the same reason. Any motorsport that requires the crowds input to pick a winner just makes me think of monster trucks lol.
