Never had any runs ins with the police, came close though.
I was tailgating a car, not intentionally, I just chose to slow down without the use of breaks to save petrol and ended up quite close to a guy who was going quite slowly on the overtake lane. He started waving his hand telling me to back off but he was crawling at this point so I refused. Then he turned his police lights on at the front and I quickly slammed on the breaks 😃
He changed lane and went behind me, was crapping myself that he'd pull me over but it didn't happen.
Other day I was 15mph over the speed limit and suddenly noticed a police car behind me when the lights and sirens started going off... quickly slowed down and changed lanes and wet myself thinking it was for me but fortunately they had something else to deal with.
