There are two main problems with cyclists and motorists on the road.
The first is drivers of vehicles who don't use their left hand mirror. We've all seen examples of motorists failing to use their mirrors properly even when cyclists aren't about. They think it's an optional extra or something you use to make sure they're looking good.
The second problem is cyclists themselves. Any idiot can waltz up to Halfords, buy a bike and set off. They may have never been on the road in any capacity other than a bus, and think they can use both the pavements and the road whenever it suits them. Oh, and those traffic lights are for motorists only apparently.
My point of view is that anyone who uses the road must have a license to do so, to indicate some level of training. Drivers of cars, mopeds, trucks, buses etc all must have licenses and insurance. Cyclists, even though they are supposed to use the road and not use the pavement, are exempt from this. Which is stupid. My point of view has been compounded by a few incidents where the cyclist caused me to change direction or stop - thankfully not resulting in any damage.
First incident was driving in the town and I came up to a T-junction. No lights etc. I'm slowing down to stop at the give way, and this f**king idiot of a w****r on a bastard BMX nearly went in to the side of my car bonnet. He was on the pavement doing some daft speed (this was at the foot of a hill). Then the moron waved me on. He, waved, me, on. As much to say "after you fella". No helmet or anything. And another incident not involving me but happened to a friend was when he came up to a roundabout, looked right to see if anything was coming, there wasn't proceeded to drive forward when he hit a cyclist. The woman, wearing nothing more than a dress (so no helmet) decided it was a good idea to cycle on the road, anti-clockwise around the roundabout.
The idea to train motorists to respect cyclists is a good idea, but it shouldn't be the only idea. It should be mandatory for cyclists to undergo proper instruction and have a license and insurance. It's only fair, and can at least mean education is being delivered to every single user of the road.
