DON'T !!!
Texting and driving is the worst, admittedly. But the next worst drivers I "experience" on the roadways, people talking on their phones. Holding it in your hand isn't the problem, so hands free isn't any better.
It's the amount of concentration one uses up listening, deciding and responding on the phone. None of those actions are as easy as they are in person.
I think ALL cell phone activity should be banned while driving. And for you tech addicted ... fools ... yes, you CAN drive, and LIVE, without using your electronic communication devices.
