The steering method for most, if not all cars. The
steering wheel stretches out, and on the end is a cogwheel. This cogwheel connects to the rear of the two struts of the front axel. When the steering is turned left, the cogwheel pushes the rack on the rear axel right. This means that the end of the left front wheel towards the back is pulled inwards, while the front part is on the
opposite side of a fulcrum, and is pushed outwards. The
opposite happens to the front right, so the wheels turn left at the same time.
