They ban some GPS use while 'driving'.   

You can pull over to the side of the road and figure out where you are just like people in cars with road maps have done for over a hundred years.  

And hands-free GPS (which is on hundreds of car models sold today and for the past decade or so) is perfectly legal.

And hands-free GPS added to the car which didn't come with it (Garmin, anyone?) is perfectly legal.  Recalculating!  Recalculating!

The chatter boxes and video game players and texters are the ones who are going to get the big tickets!  

Police officers get to give 'warnings' and 'tickets' in their discretion, don't you know?

It's called 'selective law enforcement'. 

As a  friend of mine who was an OSP officer used  to say, "Either way, it's a rock in the box!"

They often 'select' to enforce the law against the arrogant and the dangerous and let the little old ladies who are just lost off with a warning.
