Forget it I wouldn't go against it cops always seem to win, they have things in place to fuck you up worse if you go against things, like being charged with something if you go guilty it considerably drops your sentence, stand up for yourself youll be charged with all separate offences they can find and have no light sentancing. Think about how you drive, and forget it, i make a lot of road users angry because I drive under the limits. I don't seem to get any trouble. Back in the day l have earned myself a number of these for silly things all usually boosting to try and diagnose faults or set things up or trying mates cars lol. They've never taken any action against me, I've not had once for years now mind you.
