I have seen in the last months other videos that have the same results. Allow me to politely disagree to your comment.
Also, I guess we have some users here who may be able to talk from experience.
In the future once AP gets more advanced and moves closer to AP4 and finally 5 in a few years we will experience a lot of comments of people who will say its just too good to be true. Disbelieve is a normal reaction in an disruptive environment...
Would be nice if it was true, but I don´t think so. At the moment, they are limited by processing power in the AP computer - do you think they would analyze all surrounding cars´ trajectories with respect to each other when they are still busy negotiating tight corners for just one car? That would add a whole order of magnitude in complexity. In the future - totally possible, but for now - no way. One of the videos even was show out of the rear, I don´t think AP includes the data of the rear camera yet (please correct me if I am wrong here).
