I seriously don't understand why this happened. Everyone in front of him made the corner, I'd expect a "salesman" to not succumb to target fixation. Hope he's OK.
Having an interest if rider skills, I said it the first time this video came up, and will say it again. The crash occurred principally for no other reason than the rider didn't know how to corner.
There are other factors such as excessive speed for a potentially unfolding dangerous situation (failure to consider environment and traffic signs), ego to keep up with others of greater ability, but bottom line .... the rider simply lacked the skills to keep the bike under control and turn at the speed he was travelling. Just because someone can string words together for a magazine or blog doesn't mean they know how to ride.
P.S. No such thing as 'target fixation' being the CAUSE of an accident. Target fixation is a panic REACTION due to some skill deficiency in the rider (and the rider realizing they don't have the practiced and instinctive skills to handle the present situation). It is the skill deficiency that is the
actual cause of the crash, and that's what needs to be remedied. Skilled and practiced riders do not 'target fixate'. They may still crash trying to get around the corner or whatever if they made an error in judgement, but they won't just freeze up in panic.
