A method for decelerating a vehicle, a non-transitory computer-readable medium for performing the method, and reception apparatuses. The method includes monitoring a state of a driver of the vehicle, and causing a notification to be output based on the monitored state of the driver. The method further includes determining, by circuitry of an information processing apparatus and when operating in a manual operation mode, whether to cause the vehicle to decelerate after the notification is output. The vehicle is caused by the circuitry to decelerate based on the determination of whether to cause the vehicle to decelerate.
