Researchers develop new obese and elderly crash test dummies
Crash test dummies pile on up to 100lbs and are molded like a 70-year-old to reflect today's changing society of older and heavier drivers
Most crash test dummies are holdovers from the 1970s when they were designed to be 'average'
Dummy manufacturer Humanetics is now making a 273lb dummy and has an overweight 70-year-old female prototype
New dummies aim to reflect American society and enable researchers to determine how condition, size and shape can affect responses to car crashes
