Yaw rate ratio 1 second after steer out is defined as the yaw rate at 1 second after steer out divided by the magnitude of the second yaw rate peak before steer out. The yaw rate ratio 1.75 seconds after steer out is defined as the yaw rate at 1.75 seconds after steer out divided by the magnitude of the second yaw rate peak before steer out. Lateral displacement is determined by double integrating lateral acceleration from the initiation of steer (steer in) for duration of 1.07 seconds (up to ¾ cycles or the start of dwell)
