You seem like a good guy, but it's NEVER a good idea to go digging for stuff without being directed to.
Keep in mind that reaching for your wallet looks exactly like reaching for a handgun to us. Now add to that, the fact that the illegal tint makes it harder for the officer to see that you're NOT pulling a gun. He may not even need to see your ID- he might be pulling you over for your safety, just to let you know that your tail lights are out.
And although you didn't mention it, this seems like an appropriate place to mention the dangers of taking the seatbelt off without being directed to do so- I have no idea why offenders do that- the only legitimate reason we can see, is if they are going to bail out to flee and/or to try to kill us. Absolute BEST case scenario, is that you're setting yourself up for a seatbelt ticket. WORST case scenario, the officer sees you reach and then a shiny metal object (the tongue of the male seatbelt buckle half) move quickly from your right hip up and across in the officer's direction, much in the manner of a gun coming up. Again, illegal tint can make it harder for the officer to see that it's not a gun. And the legal justification for the officer to use deadly physical force against an offender, does NOT require that the shiny metal thing was actually a gun.
Rolling down the windows- good.
Shutting the engine off- good.
Putting your hands on top of the steering wheel (or even putting both BOTH hands out the window with your palms facing the officer) and remaining motionless unless and until directed to do otherwise- good.
Listening to and following directions- good.
Doing stuff that you were not told to do, especially stuff that makes it look like you may be trying to kill us- bad.
