There was another Tesla software update announced as "almost done": a major update to Autopilot 2, with an all new neural net and what not.

This all new navigation system might include functionality to help, not only the human driver, but that new Autopilot as well.

At some point Autopilot and Navigation will have to merge. Right now, both systems operate completely separate.

But if those upcoming updates will allow Autopilot to follow the navigation system changing lanes thru highway intersections, than that would indeed be 'light-years ahead'.
