There may be no self-driving wheelchairs today, but they will probably exist in a year or two. If/when they do exist, and a self-driving wheelchair were returning to its owner's home after being repaired or tuned up, would it be OK for a pedestrian to block its path, since it's not human nor currently carrying a human?
