The autopilot in planes works the same way: pilot is strongly recommended to keep hands on the controls, autopilot will release control if any conditions fall outside the autopilot's functional envelope.

Pilots are trained professionals in the field where autopilot is relevant, consumers are not.

and even though they are highly trained they still keep their attention on the plane's operation.

And pilots still make mistakes when adjusting to a context where the autopilot has unexpectedly handed control back to the humans.
