Here is my complete list of how to keep a cop happy during a traffic stop.
1. Pick a good place to stop and pull as far off the road as you can safely.
2. Turn off your engine and put the keys on the dash.
3. Leave your parking lights on if it's dark outside.
4. Turn on the inside dome light, especially if it's dark outside.
5. Roll down your window unless it's raining.
6. Do NOT remove your seatbelt, open your door, or exit your vehicle unless you are so instructed.
7. Set your wallet on the dash unless it's in a purse and you're going to have to rummage for it.
8. That's it. You don't want to mess around trying to get absolutely everything ready for the cop. He is watching you while he calls in your plates and if he sees you rummaging around he's going to wonder what you're doing and start to get nervous.
9. Don't store your gun in a spot that is likely going to be accessed. If you're going to have to get in your glove box for insurance, that's not a good place to leave your gun.
10. Sit still with your radio off and your hands on the wheel while you wait for the officer to approach.
11. When the officer approaches your vehicle, let him lead, so to speak.
12. When he asks for something that requires you to move or reach, tell him what you're doing before you do it. Officer: "May I see your proof of insurance." You: "It's in the glove box, I'll get it."
Doesn't often get me out of a ticket, but so far I haven't had anyone shoot me or even draw on me.
