Haha I've only really lost it once with a guy in a poor mans VW Bora. he soon drove off very quick when I got out the car after he was up my !Removed! when I had the kids in the car that was only a few weeks ago. I slowed down to let him pass just sat there doing that speed up slow down thing, so I gave it some beans left him by about a mile ahead, and my Missus shouting at me slowed back to the speed limit thinking that was it he knew he could keep up, few mins later back up my !Removed! again. So I slowed to 35mph wouldn't over take again so I pulled over he called me a **** so I got out and he nearly crashed trying to drive away :D
And I think you might need this Miggs ;)
