I have to admit that I use a phone whilst driving. My early model Koleos doesn't have built-in bluetooth so I snaffled a $49.00 dollar job from the internet which also plays music from my phone via my FM radio. I have a Windows phone which I have taught to understand most of what I say. Cortana will within reason do just about anything I ask, all by just moving my mouth. Considering that when driving alone or with passengers I keep up a running commentary on the actions of the fools and incompetents around me I don't see the use of the bluetooth phone or Cortana any more of a distraction, and I don't see the need for anyone else to be handling a phone in their lap when they can be using cheap voice operated equipment.
