Ive also been pulled for 'drink driving' after driving home from work after a night shift, as soon as I started speaking they automatically knew that I wasnt, fair enough it looked abit strange me driving around at 5am on a saturday morning bit I think they just gave old any old excuse to pull me over and see what I was up too, personally I think they are just a bit too nosey :P well due to work im going to be moving up north in August so hopefully wont be having the same problems up there!

i bought a book similar to this clicky mine has a green front and the picture of a copper with a speedgun on the selling page, i have leant it out so i can't remember exactly what it's called but one of the friends who's a police man has said there's nothing in there that's incorrect and it's surprising just how much stuff even he didn't know that is correct after he's checked up at work, mine was £25 and has given me enough confidence to actually stop at a copper doing mobile speed traps and tell them how wrong they are at what they are doing, i have done this 6 times now and every time they have moved on within minutes of me confronting them
