This stuff goes way back to when we used to have the old photocells on the starting line. We used to call it "shine-back". Back then, if the angle of the sun was just right it would reflect the light back to the photocell and the photocell didn't know your tire was in the beam. If you look at old pictures of cars on the starting line you would notice shoe polish on the side with the sun.
