<正>Atest car drives through a rolling Middle Eastern desert.Negotiating a sharp turn at170 km/h,the car,due to a lapse by the driver,lurches and twists,and comes to a stop badly wrecked.Spectators rush to the rescue,expecting the worst for the four people inside.Amazingly,apart from the front-seat passenger who suffers a dislocated shoulder,all three others are pulled out unscathed.
