We had a fatality here in Knoxville due to texting. A 16 Yr old girl was texting her boyfriend and here vlast text was, "I love you", before she ran off the road.
As tragic as that is, trying to cite someone for this is very difficult because you have to prove they were texting and not dialing a number or looking at there contacts.

Having said all that, WE CAN'T EVEN GET PEOPLE TO STOP DRINKING AND DRIVING!! This is just another "feel good: law that will do nothing.
