Should All Use of Cell Phones While Driving Be Banned?

Some proportion of American drivers think it's up to them to decide if they can text, tweet or talk on a cell phone while they're behind the wheel. Now, after investigating numerous crashes, the National Transportation Safety Board says that talking on wireless head sets while driving a car is just as dangerous as holding the phone to the ear, and that all states should ban all cell phone use except during emergencies.
