switch on here had a similer thing on the A1, he went past a copper on a turnbridge thingy ( the emergency type thing) and he was gonna slow down but thought at 140ish for him to get in the car and catch him,,,he was gonna get a ban ANYWAY
he went off the next junction and parked at the shopping centre and he aint heard anything,,, that was 3 years ago maybe more
