Why do you wink the wheels when you wink?
In the high-speed car, such as sitting in the roadside trees, you see in a daze only a vague shadow of the shadows. If you try to stare at a tree, quickly swinging, is not it will see a quiet scene? (Although only a moment)
The human eye is naturally blurry when looking at fast moving objects. It seems to remember that the frequency of the image received by the human eye is 0.02 seconds. If you move your line of sight quickly, the speed of sight is close to the speed at which the wheel rotates, and the wheels are "still" in your eyes.
