A system for controlling ride experiences through a ride space of an amusement park ride based on a passenger's present state. The system includes a sensor mounted on an automated trackless vehicle, being controlled to travel along a first ride path, sensing passenger data for a passenger. The system includes a controller processing the passenger data to determine a passenger state at a particular point in time during the ride experience. The controller determines a location of the automated trackless vehicle on the first ride path. The controller, based on the passenger state and the location of the automated trackless vehicle on the first ride path, determines a second ride path for the automated trackless vehicle for the ride space. The controller then controls the automated trackless vehicle to move from the first ride path to the second ride path to alter the passenger's state to enhance their ride experience.
