Every phone has a camera. Basically require the forward facing camera to be on if using the phone above X mph. From there, we should have sufficient computer vision processing to identify if someone is driving, and refuse to allow any use until given to a passenger or pulled over. Additionally we could require all phones to support the SafeDriving protocol, and there be dash mounted camera in all cars with appropriate computer vision to identify unsafe phone use while driving lock ALL phones within the car or slow car to the curb.
