If you have ever flown an airplane with autopilot you would realize you are completely wrong.

>An autopilot is a system used to control the trajectory of an aircraft, marine craft or spacecraft without requiring constant manual control by a human operator. Autopilots do not replace human operators. Instead, the autopilot assists the operator's control of the vehicle, allowing the operator to focus on broader aspects of operations (for example, monitoring the trajectory, weather and on-board systems)

You're right, and they should never have named their driving assistance tech autopilot because it gives a false impression of its capabilities.
