I was caught doing 125mph on the M1 a few years ago - got away with it
I got tugged by the plod at 125mph but they said they only had an "average speed" radar in the car rather than a camera, so cos I slowed down at one point to let another car past (fooking Audi, old git driving, doing at least 140 - but they pulled me!!!

) it dropped my average speed over the distance they tracked me down to 94.7mph. Copper then informed me if it had hit 95 or over then it's an instant ban, no questions asked

All I got was a £60 fine and 3 points

Which come off this year I think
