My method results in the window down, and me holding my ID and papers with my hands clearly visible while doing so.
Any other method involves reaching your hands into a glovebox or out of site behind you to get your wallet out. Either of which 100% of the time results in your hands being out of site which can be alarming from the cops perspective.
Like I said. Do it your way. Have fun. Again, you are deciding what to do and when and what you think is best. Not a good idea.
Its for the cop to decide to tell you when to get into the wallet the glovebox, etc.
He has a way he does things at every stop. And then he encounters you, sees you rooting around, waving things out the window, etc.
Far better to just sit there hands on the wheel, and politely and slowly respond to his commands and requests as he gives them.
