A few weeks ago, I left my house for the grocery 2 miles away. I followed a car from my subdivision to the grocery. After shopping, I followed the same car back from the grocery to my subdivision.
Of course, this points out a failure in public engineering, not the need for automated cars. (As much as I'd love to have them)
Urban sprawl is a gigantic problem that we need to address, and soon. It not only affects transportation - there's general maintenance cost, social effects, land use, etc.
