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.
I doubt anyone will understand my definition of rack and pinion steering, so I'll make it quick
Rack- on the front axel
Pinion-On the end of the steering wheel.
