This strikes me as an interesting approach that could maybe be generalized by a company like Uber. We know some of the biggest problems with self-driving cars are: - Needing extremely precise, up to date maps - Inclement weather / conditions Which suggests to me that if you chose a particular city, mapped it out extensively, and then only allowed these cars on the road during good weather conditions...you could deploy these things much, much more rapidly And of course since consumers wouldn't buy a car that they can't use much of the time or take outside the city limits, the natural use-case of this is as an on-demand taxi service, like Uber or Lyft.
