Other day, going down a steepish hill, saw a 4 x 4 at the bottom waiting to turn right.
Luckily I left a fair bit of space behind him, noticed he had rear damage halfway up his rear doors.
He then started backing up the hill, so i got straight onto the horn and left it on. Still carried on backing up, but the horn had attracted the attention of a guy walking his dog, plus another van was now coming down the hill behind me.
The 4 x 4, stopped and drove off, I didnt get his number, and before it happened I always used to say..... get the number. The shock of it, plus being glad that the idiot stopped just before he hit the front of the TF, stops the brain working.
Anyway I know have a in car camera, only £15.00 off ebay, works OK and the quality is amazing for such a cheap price.
So just a word of warning, these scammers dont have to slam on their brakes, they can hit reverse and argue they you hit them. Specially if you are alone in the car at the time.
