Before revision:  Overall, the results imply that: (1) Drivers make direct use of vestibular information as part of determining appropriate steering, and (2) motion down-scaling causes a yaw rate underestimation phenomenon, where drivers behave as if they perceive the simulated vehicle to rotate more slowly than it is.
