Why would you think it's not a problem? If your eyes on the phone they aren't on the road, I can't tell you how many accidents I have avoided simply because I was paying attention. Many of them required action that split second.
I totally agree taking your eyes off the road for any reason is a big cause of accidents. I was talking about how people slow to a dangerously slow speed on the hi way because they are deep in conversation. also how pointless the the hands free law is. Most of the time people are still taking there eyes off the road to dial and to answer(see who's calling) the phone.
I have a hard time concentrating on driving,when someone is sitting in the right seat, flapping their jaw at me. I never even power my phone up while I am driving. Trying to watchout for the D.A.s is a fulltime job while commuting these days. 
I wish more people would take driving as a responsibility, not an annoyance. I love driving, should've been a trucker. Get to drive to Philly this AM. Time to get my semi annual spinal shots. Looking forward to it, I'll be able to walk without limping again by this afternoon. Have to bring my son to drive me home. I'm in for a white knuckle ride on the way back. I don't make a good passenger. My hand will be on the e brake handle all the way home.
