Those of us who ride motorcycles, learn to watch people's heads and eyes ( sometimes in their mirrors ) and know that if you do not make eye contact, you are invisible to the others on the road.
Your last sentence sums it all up. Unfortunately it describes the majority of drivers I encounter on the road. At least in New Orleans, it seems that driving is about the 4th thing people do at the wheel of a car. Texting, eating, and dancing all rank higher on an average day. And all those people assume they will "see" things off to the side in time...
Meanwhile, I'm looking for pupils.
