Only in a movie. You never see them turn backwards in real life.
This is not true. It can indeed be seen in real life. In fact, my entire family was travelling north on a highway when we were passing an 18 wheeler (a truck). One of my kids became really excited and asked outloud why the front wheels of that truck were moving backwards! We all looked and sure enough the illusion of the wheels moving backwards was very strong! The truck had very shiney rims with many, many nuts/bolts to hold the tire onto the hub. It was a bright day and the light reflecting off the rims was pretty intense. However, the nuts looked as if they were moving in the opposite direction and thus the wheel looked like it was rotating backwards.
