I cycle around 20 to 25 miles a week in and around town and it's a very rare week that I don't have a single incident with a motor vehicle. I keep my whits about me so I've never actually had a collision and often it may not necessarily be something particularly dangerous, but just rude and inconsiderate, like the other night when someone pulled out from a petrol station in front of me to wait blocking my carriage way for a gap in the traffic going the other way. I wasn't going fast and I had plenty of time to slow and go behind her, but I'm pretty sure she wouldn't have pulled out and blocked the carriageway in front of a car, or any other sort of motor vehicle.
Mostly it's incidents where cars pass too close, this is particularly irritating when they then slow to turn off or stop to park just a few hundred feet further up the road. I once had a woman squeeze past me in her massive 4x4 only to come to a complete stop about 30 feet ahead of me and remain double parked in order to let someone out of the car, to her credit, when I gave her a filthy look as I passed, she did mouth the word "sorry" and look a bit sheepish. It's also annoying when cars pass very close on wide roads where there's plenty of room for them to move out and pass with more space between you. Where there are traffic islands, I generally move out, so that cars have no choice but to wait rather than try and squeeze through with me.
Some drivers seem to expect you to ride about 6 inches from the curb, but that's not usually viable, there's often a lot of debris on the first two or three feet of road from the curb in addition to drains that are sometimes several inches below the road surface where the road has been re-surfaced many times.
I think a large probem is, that there are now more drivers on the road than ever that have never ridden a bicycle, or motorcyle, and that have no idea how disconcerting it is when someone passes very close by at a significantly greater speed. In addition, they have less idea of how much you need to pay attention to the road surface on a two wheeled vehicle and might need to move around the road to avoid potholes, bad repairs, manhole covers etc.
