In the U.K. you get points on a license for being caught speeding (and other offence). Typically 3.

Knock 12 points up over 3 years and you lose your license.

The problem is the time it takes from being caught to getting the letter can be a couple of weeks. You could literally go from 0 points to license loss for driving 10 miles on an empty road with changeable speed limits and have no idea until a week or two later when you get 4 letters arrive.

Now until the court takes away your license you’re still allowed to drive, but it gives you no chance to change your behaviour.

That's an imperfection of the system, not a designed feature of it. It's also possible you sometimes go over the speed limit and there are no sensors around to detect that condition.
