[2021] Driving the sub with autopilot

OP probably did not mean anything bad by what they said, and there is certainly nothing wrong with wanting to clarify what you mean! Doing so merely ensures everyone gets the answers they are looking for, and there is no reason to react badly to that, I think.

I've not had a chance to find out any actual under-the-hood facts about the question, but I wanted to post a gentle reminder now: please be kind and considerate, keep things on topic and do not get into personal arguments.

I'll see if I can also find out something about the topic, too, before the week is out. Until then!
