I would expect a warning or reprimand from someone at the start hut. If there was a problem, they apparently got over it and let him take his run. Why does the guy at the bottom have to nearly come unglued? You put up good money to race at National Champs and shouldn't have to walk on egg shells everywhere and get treated like this. Imagine the roller coaster Finn Jr. just went on; he has an awesome run, (unofficially) wins, then immediately chewed out by an official...and DQ'd. Unreal. I'd be pretty sour on paying another dime to USAC.
