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

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”
Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
