just about to report a cabbie. he was in a bus lane near old street behind cyclists near a left hand turn. im to the right of him with some motorcyclists to go straight on. lights change, paralell with the cab, he decides to pull left into me, i try to move, motorcyclists have to move, i hit his cab door to stop him killing me. he predictably goes on a big rant about how im in the wrong lane, how " your lucky i have passengers here" dont you touch my cab etc. i asked him whether he would prefer me to not touch his cab and just let him run me over. i stayed surprisingly calm which is unusual... think i got his plates right but he decided to accelerate through the next amber light. wish he had to stop so i could chat with his passengers
