Should using cell phones while driving be legal, illegal, or a mix? Some countries/states have already banned this. The main options proposed are usually: 1. Banned while driving cars period. 2. Only legal if you use a headset. 3. Legal no matter what. What do you think? I'd be fine with the headset option. There are other things that are causing more accidents than cell phones though, such as eating, changing the radio, or putting on makeup while you drive.
