I was cycling to work on Thursday and was caught on the right hand side of car turning right. At the same time a fire engine was roaring up on my right (overtaking us both whilst going the wrong way on the other side of the road). The person in the car started to turn on her green turning arrow, effectively about to crash into the fire engine (and jamming me between her car and the fire truck). I whacked on her window to get her to stop, and immediately after the fire engine went by very fast, sirens blazing. Behind the wheel was a youngish fireman, utterly aware of the entire situation. He simply waved to me as he went by. It was more of a "hey, how are you going?" wave then a "phew, that was close, thanks" wave. I loved that amongst all of the noise, and potential for tragedy, he was sitting up there, waving to passers by.
