A study that looked into accident data from the National Highway Traffic Safety Administration found that obese motorists are more likely than normal-weight drivers to be killed in road crashes. Drivers with the highest body mass index were found to have an 81% greater likelihood of dying in crashes. "Vehicle designers are teaching to the test -- designing so that crash-test dummies do well. But crash-test dummies are typically normal size adults and children. They're not designed to account for our nation's changing body types," says Thomas Rice of the University of California, Berkeley.
