I agree, I was thinking back to a time, 10-15 years ago and I had to reach in my glove compartment, I made sure to verbally let the officer know what I was doing and get a response from him before proceeding. I exercised caution. In hindsight today, I would use even more caution due to all of the shootings involving vehicles being pulled over.
I can count on one hand the # of times in my whole life I have been pulled over.
First thing I do is to have my driver license ready to hand to officer, in light of everything, perhaps I will place it in plain sight on my dash. I think many people are quick to engage officers, Why are you pulling me over? ect which puts things into a confrontational situation. Why not put the officer at ease and give them your license up front, that is what he is going to ask for before he leaves his vehicle.
Secondly, Texas takes part of this out of the equation, I use to live in Mn as well as many other states, but vehicle registration is a sticker on your windshield, that in itself would stop people from reaching into their glove compartment or elsewhere.
