Yesterday's news about the train incident in LA got me thinking. We all know about the dangers of using a mobile phone in the car, but let's face it—most of us do it anyway. So, this question isn't meant to judge. I am simply curious to know how you use your phone in the car. In other words, do you stick with the mobile phone? Do you use a Bluetooth headset? Or do you have a hands-free system in the car itself?
