Unfortunaly its true that despite how well you get the car engineered.
If a traffic cop decides he wants to sticker you he will.

i got my diesel patrol stickered cause it made too much noise! Its a diesel!! they are loud.

For the most part if you get pulled over there are a few things you can do to tip the scales in your favour. This has always worked in the past. I have had several fines/demirit points reduced or dropped on the side of the road, and gotten away with warnings on a number of occasions. So it clearly works for me.

Pull over asap, but in a safe area. (obviously)

Stop the engine straight away. Dont let it idle.

Grab your license and get out of the car asap. You want to meet them half way between your car and theirs. the closer to them the better.

Always greet them with Sir/Maam. Always be cheerful, offer to shake hands. Again its all demonstration. Ask them "What can i do for YOU today Sir?"

Dont attempt to stop them from doing anything, but good body positioning will slow them down. Get inbetween them and the car, but obviously dont move to block them.

Stay calm, plead ignorance/innocense. Dont sound like you know everything.

This is about demonstrating strong body language, openness, and genuiness. If show you have nothing to hide, its goes a long way. Appealing to their vaniety will also help, hence the Sir madam, and emphasis on helping them.

I could go on about this stuff, but you get the idea.
if you have been a tool and they saw it, these techniques will still work to reduce the severity, but its best just to avoid stupid behaviour in the first place.
