Do you use your phone while you drive?

It has been proven that a person cannot talk on the phone and concentrate on driving at the same time. Talking on the phone and driving should be banned and criminal charges be brought for anyone caught doing so. How many people have to be killed before this stupid practice is forbidden.
Just awhile ago a bicyclist was killed by a driver using their phone in my area, if the same driver was intoxicated, it would have been an offense, but being impaired by talking on the phone is okay?
