This video is nonsense. Such freeway driving shown here is by far the EASIEST problem self driving cars have to solve. It doesn't require the car to recognize signs, lights, pedestrians, cross traffic, or even dips in the road. To a camera, a hill/valley looks like a curved road.
Freeways are basically flat. Surface streets have lots of hills and dips. When my Tesla Model S encounters them, it thinks the roads are curved, and starts hunting side to side, first curving one direction, then correcting the other direction.
That Tesla still hasn't fixed this obvious problem after years demonstrates they are far from solving self driving. I suspect it's Elon Musks management style, he doesn't want to hear about the intractable problems his engineers haven't solved yet.
Its when a company produces videos of their autonomous systems solving the hard problems, instead of just the easiest ones, that you know they are making progress.
