Most cyclists have no idea what it's like driving a bus or other large vehicle in crowded towns, if they spent more time riding defensively and less time trying to nip into gaps, particularly blind spots, to gain a few seconds everyone would get on a lot better.
I sometimes use a bike, suprising though ain't it how easy it is to become insular and take on an anti motorist persona when you get on the two wheels. I think the same thing can occur when we find ourselves strolling round on foot as well.
I'm also annoyed with pedestrians who at night wear all dark clothing and think just because they can see my car lights that I can see them. Get onto the pavement or into the side of the road you morons.
- ah that's better, rant over.
