If people don't use them then the cost divided by those who do must be astronomical, you can't blame motorists who are fed up being stuck behind lycra clowns listen to their iPods who believe their taxes paid for cycle paths get get them off the road, and then all of a sudden any excuse and they are back harassing motorists.
Cyclist should be fined for cycling on the road anywhere where there is a cycle path and if necessary cycle slower, because when they are on the road they cause cars to go slower! If there is a problem with the path then they should set up weekend work groups to go out and fix them, that way the cyclist who pay absolutely nothing towards the upkeep of the road (yes I know what you are going to say but this is motorists minds I am talking about) could actually do something to benefit them and others. All this nanny state that make people believe others owe them, well stuff that get out and sort it!
