That was painful to watch, I can only imagine how the guy who got run over feels.
2 questions for more experienced riders:
1) Did that guy fall "well" giving how he carried his arms in the crash? (guy who highsided)
2) I am presuming that highsider lost rear tire traction and he shut the throttle - is this the likely case and if so, had he stayed on gas, equal or harder he would probably have been OK?
I ask #2 because twice at Loudon while coming out of T3 going up the hill I had two instances where it seemed that my RPMs went up and rear stepped out ever *so* slightly . I stayed on the gas and it just came together, by the time I sensed what has going on, it was over so I didn't get chance to become ham-fisted with controls

I just dont want to end up in a preventable high side.
