I see a few perfectionists in this thread. Fact is, hot pit can and will have a number of points of concern at any given time. From humans, cones, scooters, bikes, parked moto's, tool carts, umbrella girls
ect.. ect.. ect.. Hot pit is part of the track yes, but it is not the place for speed.
He fell, laugh and move on, there is no real concern here... your local wal-mart parking lot is more dangerous.
I give him a 8.5 on the dismount though.
