Have you ever been stopped by the police whilst driving your car ?

I’ve been a passenger in one that was..we were going the wrong way down a one way street( in Llanelli).Realised and were turning round when this guy appears and screams at my friend to ‘get his licence out’.
Turned out he was an off duty copper...but not knowing we drove off.A couple of miles later -flashing blue lights and we were pullled over.
I had visions of spending the night in a Llanelli cop shop...but my friend was let off with a warning to be careful next time we were in town
