Watch sports for the crashes?

I like to think that people watch racing type sports because of the potential that there may be crash. The crash itself is pretty exciting, but being on the verge of a crash for a few hours is the big draw in My opinion.
I think the fault in this video was equal on the 2nd ,3rd and 4th rider. #3 was obviously going much faster than #2, #2 moved down the track to late, #3 was going to pass him on the inside (which would have been a bad move) but moved up too late, and went a bit too far because of his pedaling, #4 should have seen the situation that was about to unfold and given room.
