I'm not sure I really follow the logic with the auto pilot. It works on most all roads, whether residential, local, or freeways. But the auto lane change only works on freeways. I don't see the point of the auto pilot if you can't auto change lanes when you need to, whether it be a local road or a freeway. I've been told by Tesla that the auto lane change does not work on anything but freeways. Who really drives anywhere without changing lanes often? And if you need to disable the auto pilot, change the lane, and then re-engage, it all seems tedious.
