I'm not convinced it uses cameras and not GPS. My car shows the speed limit IMMEDIATELY when I turn onto a street whether I can see a speed limit sign or not. IF it is using cameras I think it is also using GPS in some way as it will know speed limit data even without visible signs in my experience.
