I pulled over 2 xmases ago in works astra. I was in the wrong. I undertook what I thought was a taxi. He flashed me and followed me through a town centre, I tried to loose him. After 2 mins gave up and pulled over. As I did a panda top pulled up with blues and 2s. Turned out not a taxi, 2 off duty officers in the station officers car on the way back in. I had a chat, apologised. Shook hands merry Xmas etc. No further action. Learnt my lesson about being patient. I'm 33 and have no points, that was my first issue. But most of the time I'm on quiet country roads. My work requires me having a fairly clean license so cruise control is my friend.
