From wikipedia: "An autopilot is a system used to control the trajectory of an aircraft, marine craft or spacecraft without constant manual control by a human operator being required. Autopilots do not replace human operators, but instead they assist them in controlling the vehicle." The important bit, which is apparently not understood by the public is that it's only used as an aid in controlling the vehicle. You still have to monitor it and be prepared to take over if it doesn't behave properly. I once flew an airplane, set the autopilot and the airplane decided to go into a rapid climb unexpectedly. That's exactly equivalent to the lane assist failing to keep the car in the lane. That said, it's clear that because the public doesn't understand what it means to be an autopilot it's a bad choice of name. Or at least Tesla should be spending a _lot_ more time educating people on what it means before they use it.
