Four-wheel steering

The so-called four-wheel steering means that the rear wheels also have the same steering function as the front wheels. They can not only turn in the same direction as the front wheels, but also can turn in the opposite direction from the front wheels. Its main purpose is to enhance the maneuverability of passenger cars at high speeds or under lateral winds, improve maneuverability at low speeds, and facilitate the adjustment of movement from one lane to another when the car is traveling at high speeds, so as to reduce the number of U-turns.
