Most cyclists are law-abiding and considerate to pedestrians and road-users.
To use your words upthread, it's a very subjective observation. I don't have any figures so I want say 'most' but many cyclists seem to think that the rules of the road are for guidance and open to their personal interpretation. I used to cycle a lot before I got my free bus pass and, like you Steve, I always followed the rules of the road. I used to find it just as annoying as a cyclist as in my car, to see other cyclists threading their way through crossing traffic against red lights, ignoring no-entry signs or cycling on pedestrian-only paths.
Our local paper is reporting that, this week, seven people have been fined for breaking the cycling ban in the pedestrianised area of the town centre.
