What is the Principle of Reversing?

[DeDavid]

When a car turns, the state of each wheel is such that most cars use the front wheels as the steering wheels, while the rear wheels cannot change direction. The radius of the front wheel trajectory is larger than that of the rear wheel trajectory because the rotation center of the car is at the center of the rear axle, giving the sensation that the car is 'swinging its head.' The same applies to the motion parameters when reversing. Here is some additional information: Reversing precautions: Adjust the seat's front and back position, and set the backrest to a comfortable angle to ensure free rotation of the steering wheel and optimal visibility of the car's hood. Then, adjust the left and right rearview mirrors so that the car body appears in the top third of the mirror, with the rear door handles visible at the upper edge of the mirror.
