Why signal out of courtesy? What benefit does that serve? Honestly it’s discourteous as it is extraneous noise that could interfere with legitimate signals.When your lane is the one merging, you should signal out of courtesy, and FSD should aspire to be "better than average human", right?
You must signal if you cross a white line - I was taught - such as a dotted white line at a merge point. This video has no line at this particular merge point (some do), but since our lane is ending it is courtesy to signal. For one thing it confers information to cars behind you that something is happening causing you to leave the lane. They are thus advised even if they are well back before the signs.
Like the signalling in / out of roundabouts, there are rules, courtesy, and some people may not know/obey any of them but they still exist for the "above average driver".
Of course my comment was in response to “two lanes merging” and not the “one lane ending” scenario you mentioned. Yes, if you are leaving your lane to enter another, you should signal.
