Johnson suggests that there will be four types of vehicles in the future: traditional cars that still require a human driver, “family autonomous vehicles” which are owned by consumers and used exclusively within a single household, “shared autonomous vehicles” (SAVs) owned and deployed by fleets in a model similar to Uber and Hertz, and “pooled shared autonomous vehicles” (PSAVs) that are like the preceding category, but which carry more than one passenger at time, like Uber Pool or Lyft Line.

Similarly I distinguish four technical-organizational solutions in automated mobility: (1) autonomous automobiles (AAa) which are the evolution of traditional self-owned car (can be fully autonomous); (2) self-driving car-sharing which differ from 1 by the organizational part — not-individually owned but personally operated; (3) self-driving carpooling/ride-sharing which links individual and group use; and (4) driverless shuttles of about 10 places, which work as the transit and complement mass transit — it may be based on both fixed and flexible route.
