Re: Distress
"All properly run ships have 24 hour lookouts"
The fallacy of that is the first part: "properly run"
The reality is that crews don't, which is why smaller boats get run down with monotonous regularity. A robot at the helm may well help reduce such issues, by dealing with the farcical claim that the current manning/watch situation is adequate (owners of course resisting anything which costs money, like detection/collision avoidance warning systems)
Incidents of near misses between ships where one of them is clearly on GPS autopilot and NOONE is visible in the bridge are fairly easily found.
