Americans are getting taller and fatter, and carmakers say it's time to give the decades old crash test dummy a make over.
Right now the standard dummy is 5-foot-9 and weighs 170 pounds. Chris O'Connor who runs Humanetics, the leading maker of crash test dummies, says the new dummy weighs about 100 pounds more and is a few inches taller.
"Auto safety is based on what we measure. We need to have a test device that reflects that growing population change."
Stewart Wang from the University of Michigan's International Center for Automotive Medicine says heavier people sustain "more severe, lower extremity injuries:"
"Safety features, the airbags and most importantly the seatbelts are designed around those dummies."
O'Connor and Wang are also developing dummies to accurately reflect older, more fragile drivers.
