It seems unlikely that it would be practical to stop all phone use to & from cars, given the way comms have developed in the past 30 years.
My road car has built-in Bluetooth with I-Drive and the screen which does everything including Nav, Warnings, Entertainment, Settings and Comms is to the left of centre in the main console. I can display my contacts list, scroll down and make/receive a call using just one control. There is also a keypad built into the dash which enables calls to be dialled without too much distraction. There really is now no excuse for hand-held calling and absolutely no excuse at all for texting and doing 'social media crap' whilst driving.
