Why so many Americans have never even heard of Uber or Lyft

Going by the headlines, it often seems as though the future of transportation is already within our grasp. Depending on which experts you ask, self-driving cars are just five to 10 years from hitting the roads. The rise of ride-hailing apps such as Uber and Lyft point to a world of super-mobility, where on-demand software combined with driverless technology will enable teens, seniors and the disabled to get around without ever needing a car of their own. Airborne drones will revolutionize shipping and logistics, while the Hyperloop promises to cut long-distance commutes down to a matter of minutes. And yet, data still suggest this future is much, much further off than media reports project.
