Simulations are being run in numerous geographic locations to assess the costs and impacts of shared driverless fleets. Such a simulation for Austin, Texas provided the following results: 19% annual ROI for a fleet operator of driverless vehicles that would charge $1/mile traveled in unshared mode (i.e., individual alone in vehicle). If I were a cab owner, I would look to sell before the driverless wave drowns me. Uber is only the beginning of the taxi owner’s headaches. Already city cab license values are declining (by 25% in Philadelphia).
