It's not exactly the best road for Autopilot. >Autosteer works well on standard highways when there are clear lane markings or a car directly ahead to follow. It does not function reliably when a road has sharp turns. [...] Keep in mind, Autopilot is a (public) beta, and as such, it asks you to keep your hands on the wheel at all times.
