Target fixation is the reason for alot of accidents, I know of two cases (fatal) that could have resulted in lesser injuries due to it.
It's why bikes hit power poles, the rider is saying to himself, don't hit the pole, don't hit the pole..............
You go where you look, if your looking at a target you will naturally head towards it.
If your too hot into a corner, don't look at the roadside, pick a point you would like to exit the corner from, and concentrate on that, most (sport) bikes will out corner all but the most insane riders ability.
It's happend to me once, scared the shite out of me, but I got round.
