Kind of off topic, but I'm still not sold on the "put your hands out the window" deal. I've had officers tell me it looks like you're trying to dispose of evidence and they'd rather see a light turn on (at night, of course) and both hands on the wheel.
I also don't get anything out of my pockets or dash until asked for it. I don't want them to think I'm hiding something or reaching for a weapon. Along those lines, I always wait to make sure they notice the gun between the seats and ask them if they want me to get my registration out of the glove box before I reach across.
