Steering in cars today have evolved substantially from the days where we all drove cars with manual steering.
They were heavy to drive and difficult to manoeuvre, particularly at low speeds or when the vehicle was stationary.
The main component we use is the same, the steering wheel, yes the design has altered over the years but its function remains the same.
It connects to the remainder of the steering system and eventually to the wheels of the car, we turn the wheel to the left and the car turns to the left, turn it to the right, the car turns to the right and at the centre position we drive straight ahead.
Many other components of the steering and suspension system ensure the vehicle behaves the way we expect it to when the steering wheel is turned.
