We live close to a highway which is posted 80 km/h. It is not a divided highway but one lane each direction with well painted outside and center lines. AP limits to 70 km/h. Is this the current limit for Model 3 for any highway that is not a divided one? It is a highway but most 'exits' are turns where people could potentially fully stop in order to turn off of the highway even against traffic. In this sense, maybe they consider all non divided highways as the same and the limit is 70 km/h?
