I would characterise my attitude to compulsory ID, registration, etc.. for cyclists as "fierce resistance" simply because it strikes me as a stupid idea - almost on a par with trying to introduce such things for pedestrians.
Not only would it be a disproportionately oppressive measure to take to tackle a non-problem, it would also cost (a lot of) money and inevitably drain resources from more important policing.
Among other things, might this have been in response to the "How to deal with the police" video that seems to have gone viral? (The one in which two cyclists, one of whom is a policeman, make utter twunts of themselves.)
In that video the policeman had witnessed an offence taking place, threatened to make an arrest but subsequently turned out to be bluffing about that. Running a red light is already illegal, but the policeman in that video found himself unable (or unwilling) to enforce the law. How would introducing another law that the policeman presumably would also have failed to enforce, have changed the situation?
