The simulations were performed using an initial speed of 60 mph (the driver had stated he was traveling slightly above the posted speed limit of 55 mph). The SIMON simulations immediately showed the vehicle going into a slide and losing control as the driver attempted to return to the original lane of travel. A second SIMON simulation was performed after making a single change: The HVE Electronic Stability Systems (ESS) Model was activated. The second simulation revealed that an ESS system would have provided the driver with the ability to maintain control, thereby avoiding the crash.
