Amsterdam cyclists are terribly annoying. But that doesn't mean it cannot work in other cities.
Like e.g. policy checking for cars speeding too much, police should also check the behaviour of cyclists. E.g. working lights when it is dark, running red lights, etc.
Though instead of checking for red lights, make sure the traffic signal changes quickly for cyclists. That's more effective.
And yes, I have cycled in Copenhagen for years and not at all innocent in this matter.
