Wow... Is that really where they intended us to store it? That's friggin awesome. I just hope wind doesn't cause it to swing back and forth and get scratched.
That does look deceptively like they thought about it. Like Bob in Security Concepts was working on it, got that far and they reassigned him to design the in console safe in the new Grand Wagoneer, and since it got that far everyone assumed someone else just did it and no one ever though to go ask Bob if he was done.
It looks like a great place but I'd be super worried about flap, flutter and grit. Get it a sock!
