Dangerous in that they allow the driver to potentially view video output while the vehicle is in drive and or moving.
I don't have the lock pick but in defense of it, the passenger could be the viewer and the driver could be responsible enough to not engage the screen.
some states if not all probably have laws regarding front passenger viewing while in motion but I doubt its fully enforced.

Shawn is right to bring it up as you should find out what the consequences are if you are caught using it in your state...

 

Not to mention killing yourself or someone else on the road.

 

I have a 2007 Chevy Tahoe LTZ with factory NAV and upgraded factory Bose stereo. w/ XM. I would like to be able to operate the NAV while I am driving without having to stop, is a lockpick what I need and if it is what is a lockpick?

 

The latest version of software allows a few more things to be done while underway while also not asking to confirm you've read the legal stuff.

 

I'm not sure opening the Nav to work while I am driving is any worse than my trying to manipulate the POI setting while I am driving to get the results I want. When I drive the freeways in LA Most the other drivers are reading books, newspapers or applying make-up.
