Why? There are plenty of videos from different people showing off autopilot and FSD, and the specific case in this video - detect other cars, estimate trajectory, do not go if you would collide - is actually rather trivial.
There have just been one too many questionable videos trying to promote FSD as far better than I know it is on Twitter. Apart from the desire to promote Tesla it has the added benefit of getting instant engagement because it presents a potentially dangerous situation on video.
