Had one exactly like him a few weeks ago. Had to explain why it was a bad idea to cut a cylist up who signaling right at a junction, forcing the cyclist to slam on. A junction that also had a blind spot either side.
Didn't like being told, apparently (even if politely). Then tried to start a fight. When that didn't work threw their rattle out the pram and blocked the road every time I tried to proeed.
Some people just won't accept loosing their own little war, will they? Never mind.
Oh got not him again.
