I’m also puzzled about what to do when FSD reaches its destination. Used the system to navigate home this afternoon and decided to not disengage upon arrival as I usually do, but just see what FSD would do. As home approached, nav displayed I had arrived and the car pulled to the curb near our driveway. I took no action, and the car stopped for perhaps 5 seconds, then began to drive past our house. I disengaged.
Similar circumstances occur whenever I arrive at other destinations. I would expect the car to pull up in front of an address, or store in a mall, stop, disengage itself and then wait for action by the driver. Instead, the car stops, but then drives off by itself, necessitating my disengagement.
I suspect I have some setting wrong, but can someone enlighten me on what I should expect?
