What's all the aggression about?

I had a really strange experience the other day with a bus driver. I was going round the lea bridge roundabout in clapton and he sorta jumped ahead and cut me up just where the concrete bit starts so it could have been nasty squishing, and it was completely unnecessary because there was a red so he wasn't going anywhere. I was pretty shocked at his driving so when he got to the bus stop i stopped to have a word. A firm word about how what he had done was dangerous and needless and stupid. and needless to say he blew off the handle and started shouting and threatening to punch me (i'm a girl) by then there was a bit of a crowd gathered and even then he grabbed me and tried to push me over... in traffic. crazy bloke. Ended up cycling really slowly in front of him while he made obscene gestures at me. quite good fun.

got his details, but dont know whether to complain or not, does anyone know whether complaining gets you anywhere?

Sounds like the driver who had an altercation with Hael. Report it.
