There are plenty of FSD videos on YouTube where the driver didn't have to intervene at all on long trips, where the car isn't just following the car in front.
Technologically Tesla is far behind since one man's ego wants to trump physics and computing limitations and its failing. Still no Lidar.
I don't care about 90 youtube videos of long drives with no intervention. I care about a million out of a million (and maybe 10 on top). Either there is something I can trust with mine and my kids life with, or I am not interested with anything on top adaptive cruise control (since I don't spend my life in stop&go traffic).
