> I imagine it's similar here. Do you want the sub to move up automatically? To fire an alarm? To dissalow a maneuver? Absolutely not. Imagine a crew knowingly pushing their vehicle into potentially dangerous maneuvers and spending those critical moments fighting the vehicle or disabling alarms.

These kind of systems typically have manual overrides. If the operator truly believes they know best (or are in an exceptional situation that the automated system cannot account for), they can override the automated system (including many, if not most, safeguards). That's design 101 when you're building critical systems.
