The rare time I do get pulled over its because of a light in the back that I didn't realize was out yet.
I have back problems so my wallet is usually on the console not in my pocket while in the car.
As soon as I am pulled over I roll down both the windows on the side they are approaching from due to the dark tint.
Dome light on if night time, and I put my left arm up on the door and right hand in the 10 oclock position on the wheel so they can see both hands as they approach.
No concealed carry yet but Nebraska is a must inform state. I know some cops will have you come back to their car and place it in their car while running checks or put it on your trunk.
