Any cycle track is a good idea. Anything that gets them off the road.
I followed one down Dan Bank this morning who decided to move from the left hand side to the right hand side of the road, without any indication, and another one who was cycling two feet away from the kerb, despite the fact that half the pavement weas painted green.
These pepole on bicycles should be insured as cars are, they should all have passed a cycling test in the same way that drivers have to pass a test, and they should be made to obey the rules in the highway code. That way the roads, and pavements, would be sa lot safer.
