I have never gotten this to work. I have a 2022 model S and a 2023 model 3. Both have only standard autopilot. If I have settings set to engage at speed limit, and I get on a road and engage autopilot below the speed limit, the car will accelerate to and hold the speed limit. It will never change after that. It won't adjust up or down at all, even though the displayed speed limit is correct. The car is seeing the changed speed limit, it just doesn't change the speed of the car. Am I missing some other setting?
