The U.S. transportation secretary made a trip to Ohio to see how cars can avoid crashes. Elaine Chao watched on Monday as government researchers showed how vehicles could hit the brakes on their own to avoid collisions with simulated pedestrians.
The work is being done at the Transportation Research Center in East Liberty, a 4,500-acre proving ground that includes a testing center for one of the offices Chao oversees: the National Highway Transportation Safety Administration.

“Innovation is one of America’s greatest strengths, and this center here embodies all of that,” she said.
