Have you ever looked in the windows of traffic as you pass? I've seen them on their phones, or playing with the radio. Using speakerphone while holding the phone as a platter near their ear, completely removing one whole hand/arm from the driving equation. Woman on the freeway doing 85 in the passing lane the other day held her phone portrait style on her steering wheel so that she could watch a movie. I've seen people fiddling with giant I-pad devices or the giant screens in their dashboards while driving, too. They play on portable consoles, dig around through the trash in their cars to find something or they are after a lit cigarette they dropped, some just look out the window to take in some scenery at the wrong time or they turn to talk to passengers. Many do not have a plan about where they are going, how they will get there, what sort of time-frame it will fit, what alternate road or corner will be a better entrance to where they are going, what they want, who they are, etc. Most people are completely un-self-aware, in any circumstance, which automatically eliminates any possibility that they might consider anyone else's point-of-view.

It's easy to catch them, they don't think anyone will look in. They're surrounded by cars and cars aren't people.

One that still stands out in my memory was a car that kept creeping in to my lane on the interstate. I sped up to get past them to see that the driver had an open BUCKET of salad between their knees, one hand on the wheel while the other held a fork, and the passenger was holding up a phone so that the driver could look at whatever was on the screen. Neither of them were looking at the road.

Folks on motorcycles and driving semi trucks aren't exempt from this type of behavior, either.
