Driving itself is a full of distractions. Reading road signage, for example is part of the driving experience, but it does draw your attention away from the physical part of driving. I have driven through Dallas twice in the past month. I am not familiar with Dallas. I did use my phone for voice navigation, but I also had to watch the signage to include speed limit signs. At no point in my travels was I less in tune with the big picture than when I was in heavy traffic in unfamiliar Dallas trying to find my way.
It is possible to safely use the infotainment system. It is possible to safely manipulate one of the 70+ buttons. It is possible to safely make a phone call. It is possible to safely listen to the radio. It is possible to safely have a conversation with a passenger. It is possible to safely hand a snack back to your child. And I dare say it is possible to safely send a text. It is not safe to become consumed by or lost in those distractions.
