Don't forget about the back though: I had a driver slam into me while stopped at a light. She wrecked 4 cars including her own and sent me to the hospital with a $25K ER bill. Took 2 years to resolve that.
I get so sick of hearing people say "It's okay: my car lets me talk hands free!" It isn't just the hands that are a problem ... it's your brain being disengaged that's the problem. No hands-free phone fixes that.
The bottom line is, no one should be using their phone and driving. If you have to use the phone, pull over.
