I seriously don't understand this disconnect. You know the word autopilot because it is a technology in airplanes. That is the only reason you know of the word.

Statistically speaking, 100% of people know that 1. Airplanes can have autopilot 2. Passenger jets still have multiple pilots in the cockpit, even with autopilot.

You don't need to know the intricacies of how autopilot functions to recognize the significance of those two facts (which I'm sure you knew) and apply the same to Tesla.
