Fair points. I'm guessing that the cyclists doing 20mph+ are in the minority currently (who knows where e-bikes etc will end up as time goes on).
I do still believe some form of highly visible identification should be seriously considered to help deter some cyclists from doing whatever they like without fear of being caught.
It's all well and good
@SexyGreyFox using a very specific example (road deaths) as an argument however things like failing to obey other relevant laws or causing damage to other vehicles may be lowered if the cyclist is aware they can be identified.
Example - if the cyclists fails to stop at a red light and gets hit by a car (non fatal) - yes, they will come worse off physically but does that negate the potential psychological harm to the driver or any repair costs to the car?
Of course, you won't prevent them all. Some motorists and cyclists won't care that they can be identified and will still drive/cycle like an idiot but if it can reduce the instances by changing the behaviour of some, then that's a good thing.
