I REFER to car drivers using their mobile phones while driving.

With all our technology we have these days, would it not be simple to put a device in all mobile phones that they become inactive as soon as the car engine has been started, therefore making it impossible to use your phone while driving?

Also all the photographs of car drivers using their phones that you printed in the Echo, surely they should all be fined as you must have their registration numbers?
