Maybe its that if someone is at the helm, it’s not going to be accidentally knocked. Ships helms (traditionally, I’ve not been in a large modern ship) aren’t in confined spaces specifically designated for operating the ship. They’re just a wheel on the bridge.
If it’s on autopilot, nobody is at the helm, and someone walks past, gets bumped or whatever into the helm. You don’t want the boat yeeting itself into land.
Go do a trade. Computers are dumb.
