I don't think this is a vent, more like an ID holder (credit cards, insurance cards, etc...). It's useless to me because it hold anything.....

That's where I keep my papers as well and it makes cops feel comfortable since there's nothing you could be reaching for in the visor compared to a glove box or center storage. And it's seeming like these days being mindful of how you reach for certain things while pulled over gives you the best case scenario.You can probably slot a paper map in there, as if anybody has any of those these days what with Sat Nav and all that! Haha! But you could also clip your sunnies in there, or perhaps like what @MarengoMac says - license and registration so you don't have to lean all the way over to the glove to dig that stuff out.
