I have city cycled for years and you have to be very alert and aware of everything going on arond you.
That said i have had 2 proper incidents occur to me While on the road.
The 1st was the dreaded bus beep, driver pulled along side me beeped and then opened doors and shouted abuse at me with it ending get on the side you K**B, subsequently i was younger then 19. So i caught him at lights jumped on bus and ranted and raved at him so much that police turned up, I was nearly in trouble only for a trusty passenger who i found out later was also a cyclist on their way to interview came to my aid, and said the driver caused it all. H e got arrested and the bus company had to get another driver to collect the bus, something to do with the fact that he had endagered passengers,
I got a letter of then Merseybus appoligising to me.
The 2nd was some woman seen me coming down a road and thought, sod it its only a cyclist, I had to swerve to miss her car (BMW) and hit a unsuspecting old lady at the lights, fortunatly it was outside and ambulance station who came to the aid of me and the old dear, after me repeatedly apoligising to the old dear she said she seen it wasnt my fault and that of the driver and not to worry. She later attempted to claim damages from me old dear turned into old b**ch
I had to goto solicitor to counter the claim and had to goto court and fortunatly i had the ambulance driver as witness to admited she said it wasnt my fault
