The usual tactic is to have enforcement staff asking people to stop and then, occasionally, for those that don't (easily radioed through) 400 yards up the road a Police car parked up ready to take on anyone who doesn't stop. It's up to you whether you want to risk trying to evade them. You might be able to outrun some random council officer, but the Police can be a little more persistent.
The Police backup won't be there every time, the idea is that you won't know whether it is there or not, it's your choice whether you want to risk it or not.
