Talking, hands free included, and texting while driving is STUPID and DANGEROUS. Everytime I'm driving its obvious who the culprits are. Sudden breaking, slowing down and speeding up at will, lingering at or stutter stepping through stop signs and lights, no turn signal, weaving in and out of their lane and etc. All the while yacking away. Unconcious arrogance at its best. 
All accidents, by law, should include phone usage investigation on the spot. Those in inviolation receive stiff penalties. Those caught off guard talking / texting while driving, same thing. I'd like to see the return of unmarked police cars patroling our streets and highways. Case closed.
