The summer before my sixteenth birthday, I was enrolled in driver's education so that the very first moment AFTER my sixteenth birthday, I would be ready to get my driver's license.  To a teen of my age and time, a driver's license was the ticket to freedom.  Not so much today.  Fully half of all eighteen-year-olds today do not have a driver's license, a fact pointed out by Jeffrey Cole, Director for the Center for the Digital Future, Annenberg School of Communications at the University of California, in one of the IAB's "Leadership Dialogues" during last week's Ad Week in New York.  Cole was talking about "Driverless Cars and the Battle for the Living Room" in his Leadership Dialogue, two things that seem unrelated but are more connected than one might think.
