That really is horrific footage to watch Andy. Made worse by the sense (and one that you must have had 10 fold!) of what is about to happen. Seeing the car move forward and knowing you're going to hit it. I'm darned pleased you came out of it relatively unscathed.
To change tack a little, in hindsight do you think there's anything you could have done to avoid the incident? (Short of not having gotten on the bike that morning!) Was there any tell tale signs that you recall, any spider-sense or uncertainty about that car? I think if you have any insights, or things you'd do differently next time, it'd be really really useful if you could share them.
It's my biggest fear at junctions... if I can't make eye-contact with a driver (for whatever reason), I become uncertain as to their intentions... and even when I DO make eye-contact, I'm not always sure!
