Banning cell phone use in cars v. banning bad driving

There's been some talk lately about making it illegal for teenagers to drive and talk on a cell phone at the state level and for all drivers in Houston County.

Here's the law as it exists now. Thanks to Susan Sports at the Department of Driver Services for looking up the code cite. It's OCGA 40-6-241:

A driver shall exercise due care in operating a motor vehicle on the highways of this state and shall not engage in any actions which shall distract such driver from the safe operation of such vehicle, provided that the proper use of a radio, citizens band radio, or mobile telephone shall not be a violation of this Code section.
