I just picked up my SR+ non-FSD model 3 last week. I have been testing out autopilot. So far it can only auto steer to keep me in lane and keep up speed on highway at safe distance I set up from the car in front like adaptive cruise control. What other features are there when autopilot is enabled for non-FSD model 3? I saw auto lane change on some youtube video but I cannot seem to work so maybe it is for FSD?
