Since it got lost in the merge:
Excellent holder for your Drivers License, Registration, Insurance Card, and Concealed Carry License so you don't have to make any suspicious moves if stopped (especially when carrying).
Seriously, think about it. It's in plain view and you're not reaching for anything on your person or in the compartments in the vehicle. The way things are today, it's a smart way to carry these items when driving. When you leave the truck, just pull and put them in your wallet or purse. At least it gives me peace of mind that there will be no "I thought he was reaching for a weapon" accidents. If you think about it, the GM designers/engineers were really smart putting this in.
