Whatever is said about his riding if you slap that video full screen and put it on 720p you see just how long that car could/should have see him. I think the speed is irrelevant to where to attribute fault the car driver is guilty of deadly incompetence. Maybe the speed is relevant to the final consequence (death) though I wonder if he had come off at 60 and headplanted that hedge/tree would he have fared any better.
