Do you use your smartphone while driving?
Depends. While texting and driving is idiotic, dangerous, and illegal now in most states, talking while driving is dependent on the skillset of the driver. I believe that most drivers are very capable of talking on the phone and driving safely. However, there are others who are driving 5-10 miles per hour under the speed limit, making illegal turns, not paying attention at stop lights, etc, because they have a phone stuck to their head and are incapable of doing two things at once, like walking and chewing gum.
