Haas CNC Racing NASCAR team owner Gene Haas teamed up with Jacobs Engineering to create the first rolling road testing facility in the United States known as WindShear Inc. It's a one-millimeter thick continuous steel belt that rolls at over 180mph, and features sensors under the bed that can take readings at each wheel. It was created because wind tunnels get errors in readings at such high speeds. Although I'd much rather deal with reading errors than have a test car go shooting through the wall because the wheels and belt weren't exactly matched up.
One more shot after the jump.
