Popped to Tesco's over lunch and coming back we were following a marked up traffic police car. A young lad tanks up behind us in his Saxo and just overtook us.

Once he was alongside and his mate was staring at us they saw the police car who also saw them and the blue lights went on fairly promptly.
I don't know what the lad was paying attention to but it sure as hell wasn't what he should have been.
