| This would never be implemented I realize but here is a possible solution: New law: driver's phone must be in semi-disabled mode The phone can already infer it is inside moving vehicle. The bigger challenge is, how to determine the phone belongs to the driver? Say N passengers in car (including driver), each with cell phone. When phone infers moving vehicle, it attempts to mesh with other phones in the vehicle. If N=1, driver is solo, phone semi-disables If N>1, phones ask users to vote on who is the driver. Result: 1 phone disabled
(Voting tie disables both/all) The only inconvenience here is to a passenger with a phone-less driver. |
