This is pretty much exactly how autopilot works in aviation. The pilot sets the autopilot, and it flies so long as it can understand and react to the conditions it can sense. If it detects bad input, or a condition it isn't programmed to handle, it hands control back to the pilot. Generally planes don't fall out of the sky just because the pilot has control again when he didn't expect it.
