What causes the wagon wheel effect?
You may have noticed that when the vehicle is moving, the wheels spin backwards on film and television. The Wagon Wheel Effect is a result of undersampling and aliasing. A rotating object can be seen on the left side of the figure.

The reverse rotation effect is a result of spoked wheels rotating backwards when reaching a certain speed. When the shutter opens, the spokes will appear to be in the exact same position every time.
Why do spinning things change direction?
The Stroboscopic Effect or the Wagon-wheel Effect is the reason for it. Our eyes have a tendency to capture 20 frames per second and the wheels of the car rotation at a higher rate and the images persisting per frame may make you feel if it was rotating the opposite way as each frame may be in a different position.
