When I test-drove a Tesla last year, the system gave the impression of reacting to the outside environment instead of predicting it. It was always later in applying a correction than I would have been. It would drift towards the next lane, and while not at the exact last moment - it would steer back slightly after what I would have done. Not confidence inspiring. If it had been an option, I would not have paid for it.
