I think I am in a similar frame of mind to Vic on this one. I have, over the years, built up a serious dislike of cyclists. I recognise that my dislike has shaded into outright prejudice!
My issue comes from my dual role as pedestrian and motorist. I like to get a walk in most days and I am lucky enough to be able to walk to the paper shop, doctors, chemist, Co-op, pub etc. As a pedestrian I, and many others locally, feel persecuted by these entitled morons who cycle at speed on the pavements in contravention of the Highway Code. The worst thing is when they come up behind you at speed and pass you by no more than an inch. The police take no action but, worse than that, our local council refuses to put up signs telling these idiots to get off the pavement or face a hefty fine.
As a motorist I have fewer issues. Cycling 2 abreast being the main bugbear. I tend to think that those cyclists that actually do use the roads are more aware of right and wrong - that may not be the case everywhere I'll admit.
Putting my dislike aside for a moment, I genuinely do feel cycling should be encouraged on health grounds (exercise for the cyclist, cleaner air for the pedestrian). I'd like a carrot and stick approach - the carrot being investment in cycle lanes separated from the carriageway by a kerb and the stick being a £1,000 fine for cycling on the pavement.
