A learning system for an automated vehicle to learn local traffic customs includes a location-detector, and object-detector, and a controller. The location-detector indicates a location of a host-vehicle on a digital-map. The object-detector detects a lane-marking and other-vehicles proximate to the host-vehicle. The controller is in communication with the location-detector and the object-detector. The controller is configured to determine when an observed-behavior of the other-vehicles is not in accordance with the lane-marking present at the location, and operate the host-vehicle in accordance with the observed-behavior.
