Yea Autopilot is just adaptive cruise control on every other car maker. Such an awful term. Full self driving is the in city driving, negotiating stoplights, turns etc.
I think this is only confusing because most people’s only understanding of autopilot is what they watched in movies when the pilot flicks a button and leaves the cockpit go fight a villain so they imagine autopilot means FSD which it isn’t at all in its original use in planes either.
