Can't believe no-one's mentioned other cyclists. I appreciate I'm in danger of becoming some sort of cyclecraft-spouting bike Taliban but I can be out from the kerb making myself large enough for the cars, buses etc to see me and have to think about passing me correctly and then some tw*t can try to cycle up the inside of me

.
I can normally anticipate what a vehicle is likely to try to do to me by judging the road layout - e.g. left turn up ahead, so watch out for left hookers and cover the brakes - but cyclists can move quite erratically (I do expect I'm not entirely innocent of the charge myself sometimes

).
Add to that all sorts of other faves such as RLJs, appearing off of pavements, bad lane selection at junctions, not looking over their shoulders....
I probably only notice the actions of other cyclists more as we're the only ones going at more than walking pace
