If I program my Bendix-King autopilot to fly heading 270º at 4K feet and there's a 5K foot mountain directly west of me Bendix/King autopilot has a feature called Enhanced Ground Proximity Warning System which would be hard to ignore. Some models have "terrain avoidance maneuvering" which would actually prevent it.
