As title says ive just been pulled by an undercover focus in redcar, was behind a ford ka who was doing about 15-20mph in a 30 and got impateint so overtook it, stupid of me i know, i should have just waited. Little did i know, the car behind me was an undercover car. He followed me home and asked if it was me that was just overtook the car. So i was just honest and said yeh, and told him the car was going slow so overtook it. He just said be careful over christmas and think next time. Was very lucky.
