Matthew Crawford, author of the new book “Why We Drive:Toward a Philosophy of the Open Road,” says that once we were drivers, the open road alive with autonomy, adventure, danger, trust, and speed. Today we are as likely to be in the back seat of an Uber as behind the wheel ourselves. Tech giants are hurling us toward a shiny, happy “self-driving” future, selling utopia but equally keen to advertise to a captive audience strapped into another expensive device. Are we destined, then, to become passengers, not drivers? He says that much more may be at stake than we might think.
