Thats what I do.
And I have my CCW in hand before the officer makes contact.
It takes him about 30 seconds to know that I am the good guy.
And if you can, get out of your car and start walking towards his, usually with your drivers license in hand or be in the process of pulling it out of your wallet. You have to act fast or he'll get on the loudspeaker and tell you to go back to your car. Luckily, they always call in the license number of a car they are pulling over and that takes a few seconds.
If you can make it past the end of your car, and have your license in hand, he or she will frequently let you bring it to their window and then tell you to get back in your car.
He'll run your name for warrants, put on his hat and walk to the window of your car. If he sees nothing suspicious, you have about an 80% chance of a getting warning. A retired cop friend of mine gave me this plan over twenty years ago and my last five encounters with traffic cops have ended with warnings.
And far as what rights I have to and could assert and throw in his face - I'll take no ticket anytime - thank you.
