What I expect it to do is to be a courteous driver, and back off a little bit to signal to the car in front that I got the message and that it's safe to merge.
FSD is already defensive to a fault, with frequent stop-and-go indecisions of when to merge onto a highway, but that's a whole other story.
A major part of safe driving is about being predictable. You either commit and claim your right of way, or you don't. In this situation, both can be signaled easily to the other party by being a bit of a jerk (e.g. accelerating to close the gap and prevent somebody else from merging) or the opposite. Both are better than not doing anything at all and keeping the other dangling in a state of uncertainty.
FSD is in an almost permanent state of being indecisive and unpredictable. It behaves like a scared teenager with a learner's permit. Again, totally different than my experience in Waymo in the urban jungle of San Francisco, who's a defensive but confident driver.
