Angler Bob --> Cui Bono? Your comment is ambiguous. Where do live? Do you cycle? Are you affected by errant and wayward cyclists? We are, on a daily basis and if there are trouble makers, which there, we need a way to identify them, such as a description of a license plate. Not all cyclists are law abiding, accountable, or even nice for that matter, some are even rabid in behaviour. Do you live in a city? Where was this approach tested? I personally think you are full of kaka.
