I dunno, but as he is driving...err flying NOE on the left hand side of the road, it is well possible that this was filmed in Australia or another country, and the line drawings may be strongly different from the US roads.
Besides, the length and separation of the white lines on the road seem to be pretty big at the beginning of his run.
And about the tachometer, somebody said on the forum where this video was posted that Hayabusas have the tachometer reading speed on the transmission between gearbox and wheel.
Anyway, if the video was doctored, it's a hell of a job.
