It can work, if your willing to play the yes sir no sir 3 bags full sir thing. A copper pulled me over for driving with a map on my steering wheel, after the usual bollocking i was expecting i just took it all, and tried not to let any "attitude" cross my face. He was on about i could give you howver many points for this, he eventually let me off, and gave me directions to where i wanted to go. I was fuckin amazed, all my other encounters with coppers theyd shown no heart, fuckin huge credit to that copper for letting me off.
