I only really get annoyed with cyclists when they do stupid or dangerous things, but then I get annoyed with car drivers for the same reason. Like one guy waiting to come out of a side turning, my bus is the only vehicle on the road, nothing behind me for miles. I'm thundering along between 35 and 40 (on a 40mph road). Mr Cyclist decides he can't wait 10 seconds until I've passed the junction he's pulling out of, no he decides it's better to pull out infront of the bus, forcing me to have to brake hard to avoid flattening him!
I don't really have a problem with cyclists they are on the road and if needs be I pass them wide and carry on without further ado. But my other half gets really wound up about them for some unknown reason. Just the sight of a cyclist, particularily ones wearing lycra gear, really winds him up. He starts swearing and grinding his teeth. I really don't understand it, especially in most cases the cyclist hasn't done anything wrong, and has even stopped at a red light. Mind you I've found since he's become a coach driver his driving has become agressive all round.
