The drivers of two luxury supercars were attempting to show off their vehicles at high-performance levels on a divided highway when one of the vehicles went out of control and clipped the other vehicle. Although the impact was relatively minor, it was enough to destabilize the vehicle traveling at high speed and direct it off of the roadway where it rolled over numerous times. Even though the driver was seat belted, the roof of the vehicle intruded into the occupant compartment causing a fatal head injury.
