English is a consensus based language, not a language ruled by any official.

Words mean what people think they mean. Definitions are what the author of the dictionary thinks people think they mean.

Unless you're going to spend the time and money and effort educating people on what a word might have once meant and what you would like it to mean again, you're kind of stuck with it. Tesla has absolutely chosen AutoPilot as their name because they know some people will think it has more capability than it does because some people don't know most plane's autopilot is fairly dumb.
