I'm confused why there is such a dissonance on the definition of "autopilot." Most people are fully aware that commercial planes have at least one human pilot in addition to an "autopilot," and I think the passengers on the plane would be very unwilling to fly if the human pilots weren't present. "chauffeur" seems like it would be misleading for partial self-driving software, but "autopilot" seems spot on: helpful, but not good enough to replace the human.
