The human eye can instantly recognize the available driving paths, the motorcyclist ahead, and project where people will walk. Software would have to parse out where the open roads are, how far that motorcyclist is and whether he can clear the intersection before the car reaches it, and what that sign on the right-hand side is—using the same information, but it has to parse it first whereas we do that almost instantly. It's a totally different game.
