Abstract
In a recent article about global trends in injury, Sally Murray describes prevention efforts for traffic-related injuries, but 2 independent trends in the developed world may reverse some of the improvements that have already been made: the aging of the population and the increase in the use of sport utility vehicles (SUVs). Despite improvements to newer passenger vehicles to reduce the effect of collisions with larger vehicles, including SUVs, concern persists regarding the greater risk of injury to the drivers and occupants of passenger vehicles and to pedestrians during collisions between vehicles of differing size and mass (these factors being the chief determinants in severity of injuries).
