A crash dummy sits in a 2006 Buick Rainier Tuesday, Dec. 5, 2006, at the new General Motors rollover crash testing facility at the GM Proving Grounds in Milford, Mich. The $10 million facility will be used to study ways to reduce injuries and deaths in rollover crashes by developing sensors for air bags that can help protect occupants in a rollover and help keep them from being ejected from the vehicle.
