I was once caught behind a prick doing 40 in the outside lane of a dual carridge way, this went on for two stretches and thought bollocks to this so undertook him f-ing and blinding as I went past! The car followed me in to asda car park got out and it turns out the car consisted of two undercover police officers! Haha, they threatened to take my license off me! So I told them what I thought and got a move on! Pricks
