Except in aviation trained pilots with at least a decade of experience flying planes get to use it, understanding well the limitations and purpose of the technology. A teenager can use Tesla's "Autopilot".
You only need ~40 hours (minimum) of flight time to get your private pilot’s license. This isn’t even much different than driving license requirements, except that planes are a lot more expensive to rent and operate.
(And for the record, teens can also use autopilots on airplanes since you can get a student pilot’s license allowing you to operate a plane by yourself at age 16. Roughly the same number of hours of supervised instructional operation as getting a driver’s license.)
The issue is that the general public think of "Autopilot" as the magical piece of technology that automatically pilots thing while you sip a pina colada and otherwise switch off mentally.
What the 0.5% of people who actually know what is required of the flesh and blood pilot when using an aviation autopilot is not the issue. It is what the majority understand.
Changing what Tesla is allowed to call it is the path of least resistance rather than trying to educate the general public on "what the team actually means in the industry that made the term famous and therefore should be universally applied elsewhere".
Yeah, you're going to have to provide some evidence of that, not just assertion (as common as that assertion may be on HN).
The word "autopilot" has a well-established definition. You might think "automobile" was a fully automatic vehicle.
