Public-private partnerships for roads might begin the erosion of the public right of way. But it’s also possible that autonomous vehicles will all but require limited access to public roads to operate effectively.

Today’s self-driving cars have to be designed and programmed to interact with messy circumstances. Pedestrians, dogs, bicycles, human-driven vehicles, and other obstacles all pose challenges to robocars, and if autonomous vehicles are even modestly successful, avoiding collisions with fallible human drivers will prove a temporary problem. … The more self-driving cars there are on the roads, the less complex and more predictable the overall behavior of traffic becomes.
