What I find revealing is it utter inability to reset to a safe position. It stays in the wrong lane; is it because it can't rejoin because the lane is occupied by the unicyclist (looking at the video it does not appear to make efforts to go back) ? or because it has already forgotten the context and is now driving happily in a lane ... It only stopped when its path is blocked ...
