Dorothy Levitt’s Rear-View Mirror

Origin
Dorothy Levitt was the first British woman racing driver, holding the world's first water speed record, the women's world land speed record and then longest driving record. After she first learned how to drive, she taught women including American socialites and the royal family how to maintain and operate their vehicles, astonishing men of the time. She also suggested for drivers to carry a small mirror to see behind traffic, using the rear-view mirror before the major manufacturers.

Effects
Placing within any vehicle causes it to automatically attach itself to the exterior frame and hold steady like a rock. When needed, it will cause the craft to move faster than normally capable for a short period of time.
