Next thing, drivers will need a "good pass" at GCSE Maths (or whatever its called nowadays) to prove that they can cope with the concept of an "average speed" camera...

It’s the ones that brake hard for them that get me.

Its why you have an "Average Speed" setting on your white van computer.   Reset passing the camera, pull out to overtake get past the traffic then brake and dawdle until your average is back to the Delta by the next camera, stop if you have to. Its about keeping a clean license and sod safety.
