I hope we are all in agreement that there are certain members of the car driving fraternity that through their actions give the law abiding vehicle drivers a bad reputation amongst the cycling fraternity. Likewise there is a group of cyclists who through their actions tarnish the reputation of law abiding cyclists amongst the driving fraternity.
The problem is the car driver who flouts the Law can be identified and brought to justice as the vehicle can be identified.
If cyclists wish to improve their reputation of perceived widespread lawlessness amongst the vehicle driving and pedestrian fraternity then they, or others, have to come up with a system in which the cycling louts, who are tarnishing the reputation of the many , can be identified and brought to task for their behaviour.
At the moment formal registration of all bicycles/cyclists is the only methodology on the table.
So the question for all cyclists is " What alternative methods will enhance your reputation as law abiding road users "?
Just saying No to bicycle registration will not address the problem.
