Couldn't we already have self driving buses if we just put them on tracks? They go a predefined route anyway :)

  Roads are cheaper than rails, and easier to change. Buseses on wheels are more flexible than trams or whatever on tracks, and can route around a collision. Rails in the road are a severe hazard for cyclists and somewhat hazardous for pedestrians.
