    On my model 3 I notice that the autosteer is limited to only 45 mphs on highway 19. Most of the road is 55mphs speed limit. Has anyone been successful with using autosteer? I know it is still in beta but I thought as long as the camera sees the speed limit sign it will automatically adjust?

    Thank you.

    Have the updates changed this speed limitation? I am awaiting my model 3 and will be driving it on 19 and 11 often.

    I recall reading somewhere that autopilot / autosteer will limit the speed on undivided highways.

    I notice this driving on Kalanianaole Hwy in Hawaii Kai. There's no AP/AS speed limit for the entire length going kokohead bound from the end of the H-1 until you hit maunalua bay, where the divided highway ends. Then the autopilot automatically drops down to 40 mph after you cross the bridge, and nothing I do will override the limit

    It's only because the car doesn't know the speed limit. In cases where a speed limit doesn't exist in navigation, it limits you to 45.

    I had the same problem on Kauai for most of my drive.
