Very interesting thing, Just out of curiosity I am wondering if this is similar to what I observe at a 4 way stop(signs not lights) that I go through every day where I work at.
I do the same thing... I just slow down slower... and lengthen my stop until after they have stopped. Around here, everyone is in a hurry and they will see me still creeping up to the stop line as an opportunity to GO. YMMV.
Dunno, it just looks to me like he just lost his nerve in the corner, or just pulled his gaze off the road to something else. He certainly was not looking through the corner. If he quits riding, well, good riddance.
