Both in my old redtop Astra...

1) Biiiiiig bit of liftoff on a junction in Brum centre early ish one morning, set of traffic lights on to a one way road. Did the junction, got boot down then looked in my mirror and saw a T5 sat at the lights ready to head in my direction. I just pulled over and waited... got a bit of a bollocking and that was that!
2) Way home from PVS last year, 3 figure speed down the M45 with the middle figure being a 5 - went past an unmarked Beemer which rather luckily had faulty camera equipment and 2 hungry coppers on board. Got told I was a cunt and should be going to prison
