Nope - thankfully. I spotted some road speed sensors and cameras and I'm not sure how good I was being at the time. So I was pretty worried for a while. Not heard anything yet.
So far I have had a clean licence and intend to keep it that way!
The only time I got stopped by the police was when I got lost in London and went through a secured area 4 times - they thought It was suspicious. The policeman was due to go off duty and escorted me to the road I needed
So they are not all bad!
