Autopilots in airplanes are kind of dumb (keep heading, speed, and altitude, they won’t do much anything else), which is why Tesla doesn’t use the name as branding for its full self driving software. People at least know that much.
But then again even on HN people like parent think that autopilot is the same as full self driving, when it is and always has been just smarter cruise control. The payout was for autopilot (a feature that most new cars have these days under various names), not full self driving.
