Abstract: A vehicle subject to autonomous operation includes one or more autonomous support systems configured to support autonomous operation, a feedback system configured to provide feedback in an interior portion of the vehicle and a confidence appraisal system in communication with the one or more autonomous support systems and the feedback system. During autonomous operation, the confidence appraisal system monitors, based on operational statuses of the one or more autonomous support systems supporting the autonomous operation, confidence in the autonomous operation, and operates the feedback system to provide feedback in the interior portion of the vehicle.

Abstract: Headlight leveling systems and methods are described. A determination can be made as to whether an input corresponding to a loading condition of the vehicle has been received from a vehicle occupant. If an input corresponding to the loading condition of the vehicle has been received from the vehicle occupant, a headlight level setting can be determined based upon the input. Further, an orientation of a light emitting portion of a vehicle headlight assembly can be caused to be adjusted based on the headlight level setting. Manual lookup of a loading conditions correlation table by the vehicle occupant to determine a correct headlight level setting can be avoided. In some instances, responsive to receiving a signal indirectly indicative of a potential change in a loading condition of the vehicle, a prompt can be presented to a vehicle occupant to provide an input corresponding to the loading condition of the vehicle.
