A few comments from me.
I knew he was there and i suspected where he was looking to go given the speed he was carrying. Despite that, i decided to hold my line, A: Because i'm a twat (yeh, i probably could have moved to the middle, although it happened fast and i did kind of expect him to yield), and B: Because i had no idea what was to my left or behind me. Looking back, though, he definitely saw me, and i think he wanted to try and bully me out of the way.
My reaction getting off the bike is embarrassing, but in my defence, i thought he was trying to drive away. Also, my foot was in fecking pain! (it had just been squeezed) so i was pretty upset, hence my reaction to the very kind driver letting me cross in front of him. It was after that i calmed down and decided not to make a big fuss and be rationale (hence all the 'mates' toing and froing).
All in all, after sending the other driver the footage, he relented and coughed up. New peg on order.
Anyway, there you go. If you haven't already, invest in a helmet cam.
