I'm also very surprised the helm doesn't override the autopilot, or cancel itself if there is a conflict, in much the same way aircraft autopilot or cruise control does.
This really does sound like an appalling design to me.
Exactly, industry standard is for local stop (HMI stop) to override any and all start commands unless there is a very good reason to not stop that device.
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.
