My sister, as a pedestrian, was in a collision on the pavement with a cyclist. He knocked her over and didn't stop and she is still unable to walk properly. I almost collided with one who had jumped a red and came round a bend. I have always been wary of cyclists - you see them in your mirror and then they disappear as they weave in and out of traffic- the highway code says you should treat bike riders as small cars- pity they don't behave like them!
