Neither of us were there so we really cannot assume. While riding fast it is possible to target fixate. Your claim that he was speeding and that's why he took the turn too wide....well then explain the guys at the track!

They take tight turns all day long but they are looking THROUGH THE TURN (hence their heads angled in a cock-eyed position) and that is why they don't have a problem negotiating it! If they were looking at the ground rather than UP and through the turn, then they might be slowly drifting off the road!
It's OK, I'll forgive your logic because you ride a geezer glide which is meant for cruising rather than cornering
