One has to believe that DJI have a similar vehicle under development. Speaking as a long-term pilot, the computer assisted flight control developments of the last few years make this vehicle class inevitable and what virtually everyone will be "driving" in the future. If a Phantom or Inspire can do it, it is only an issue of scale, safety and liability. All of those are solvable.
