I believe there will have to be expertise in installing these units.

What I mean by that....say for instance the Big Car manufacturer's decide to put it in all Cars.

If it is easy to install...then teenagers will find a way to dis-connect it and text and e-mail all they want and have Head-on Collisions.

I don't think You are really into believing this is the best APP out there for Safe Driving on all U.S. Highways?

Or any APP for that matter!!
