LOL -- yes, you have figured us out!
On the question of screen rotation: I have tried to keep the mount as rigid as possible, and also maintain plausible deniability when it comes to law enforcement. I know I am pushing the limits with this "navigation system" so is made sense to make it look more like a system that is setup for the car/passenger.
My friends in law enforcement have made it quite clear, they don't care if it is a 42" screen... if I have a movie playing and it's viewable from the driver seat... they can write a note to my mom and the local judge. (Your local laws may vary)
We have also talked about the navigation portion of it... the only law on the books (GA/FL) that applies to Navigation, is the distracted driver laws... and these are open to interpretation by the officer/Judge. So, if they see you weaving (even within your lane) they can stop you and write you.
So, if you are eating a burger, drinking coffee, texting on your cell phone, smoking... etc
focus on the road first.
