This technology has more than likely saved your life if you ever flown in the rain. Or driven in California. Developed by NASA's Langley Research Center's Safety Groove program, safety grooves were made with the goal if reducing hydroplaning by aircrafts on runways. The grooves in the road help dissipate large amounts of water, allowing tires to have greater contact with the roads surface. It was so successful, the technology was adopted by 800 of 1,500 commercial airport runaways in the U.S. Some states like California have adopted safety grooves for its highways that experience high amounts of rain.
