Here in the States an adult is required to have a state issued ID or Drivers license on them at all times. You can be arrested for not having a legal picture ID on you. Cops don't take your driver license away from you when they give you a ticket.
Cops used to beat the hell out of you if you talked back to them. Then they would arrest you. Once they got you to the local jail, you would be lucky if you didn't get what they called an elevator ride (stopping between floors and beaten) on you way to your cell. If you rode a Harley you got the crap beaten out of you just for being a "biker." Now most cop cars have cameras on them. Keeps the cops more honest. The cops will still ruff you up if you talk back to them during a traffic stop. They just get you out of the sight of the camera first.
I make a habit of waving or saying hi to all motorcycle cops when I ride. If they know you or your bike they usually don't bother when you go screaming by them on the road. Especially when you've said something nice about their bikes. It's easy to out run a cop car, but you don't want to try to out ride a motorcycle cop.
And if all else fails, a little cleavage still goes a long way when it comes to getting out of a ticket!
Officer did you see that sparkly???
