Totally fair. Things I might find challenging as a human unfamiliar with a given location (though GPS tends to help a lot) are probably different from an autonomous vehicle dealing with a lot of borderline crazy behavior by other cars, cyclists, and pedestrians darting out into traffic. A person also can just process so many inputs at once so you get into situations that are challenging in part because so much is going on.
