“Listening is another type of mental distraction. Whether you're listening to someone on your phone, having a conversation with someone in your vehicle, or listening to the radio, it keeps your focus away from driving. 

It's a fact that people tend to go on "auto-pilot" when performing routine activities like driving. In this situation, you may miss seeing something, even if it's directly in your line of sight. This is called inattention blindness, and it is one of the major causes of human error and crashes.”
