I quite often use my phone when I'm driving, after all many new cars have bluetooth compatability, so synchronise your phone and away you go, no taking you hands off the wheel to hold your phone to your ear so nobody even knows you're on the phone and no different from talking to a person actually in the car with you. I am however in total agreement with you about the number of people you see driving while using the phone, unfortunately while it is a law that needs to be enforced, you'd need a dedicated squad nearly as big as the police force we've got now to do it and we all know that will never happen.
