Simply put, NO ONE has a "NEED" for using a phone in the car.
Would you think it okay that an airline pilot was talking to his broker while piloting a plane or a gasoline tanker truck driver talking to his girlfriend at 70 MPH?
Driving requires complete attention to ensure safety, and to think that we NEED to pick up the phone and divert our eyes and minds to a device in our hands is patently absurd.
