The truth is seldom found in extremes!
So although I can agree with Don about the 'cycle fascists' who think motorists are inferior species (just as Peter Tatchell used to piss me off with his obvious contempt for straight people), I still think a lot of motorists need to get out on a bike and see how the other half lives. They should see cyclists as road users, rather than just a nuisance (and the same goes for tractors and the like).
I don't think getting a scratch on your shiny expensive BMW Cocoon or Ford Airbubble really compares with getting your skull fractured because somebody was only half paying attention. I used to take my bike right into Edinburgh every morning and unless you made eye contact with the driver when pulling out to pass a car, or using a roundabout, they would more or less assume you didn't exist. Same goes for the diddies who just throw open their car door without checking the mirror.
I still try to use my bike but I would never take it into town now. I would like to think that my experience gives me a bit of respect for cyclists, so that for example, I give them a wide berth on the open road rather than just squeeze past when there's oncoming traffic, unlike so many motorists who are just in a hurry to get past at any cost (to get to their next traffic jam as soon as possible).
