Have you ever noticed that with a double rainbow, the second, inner rainbow is fainter and has the order of colors reversed? This is because the light bounces around inside the droplets a second time.
Did you know that the first time a car used a rear view mirror was in the first Indy 500? Ray Harroun won since he didn’t carry a mechanic like all the other cars. You can look at the mirror in the museum at INDY. http://en.wikipedia.org/wiki/Ray_Harroun
That first race took 6:42 since they averaged nearly 75 mph, not the > 225 mph these days.
