Interesting video. I'm skeptical drop-in humanoid robot driver approach. Compared to a conventional AV, it adds additional failure modes, and reduces the vehicle capacity by one seat.
Human teledriving is a neat idea, but I'm not sure that it is a good stepping stone towards full autonomy. It almost seems like it could be the worst of both worlds.
Those Korean buses looked pretty cool. I like how the passengers were nervous at first, but quickly found it mundane.
