Totally agree
Point but doubt it will be a ban.
Most people would slow down after one flash.
Speed limits are there for a reason
When I was younger and foolish, I often drove faster than I should.
From the age of late 20's, even before the 20mph limits, I had driven lot slower in side streets and built up areas
What many fail to understand that the 'speed limit' is the LIMIT, the MAX and you can be done for driving within the limit but booked for careless/dangerous driving if conditions are poor and the speed limit is not safe at the time.
I've seen people come down side streets in their usual clownish style ie breaking last second at junction as often they have no intention of stopping, but with wet roads, snow the clowns then cause an accident on the main road they slip into. That is careless, dangerous driving.
You will get points if it is as you say and you have no outstanding points
