Some heavy automobiles without a power steering system tended to have heavy and slow responses requiring hand-over-hand turning of the wheel by the driver, and the knob allowed the driver to "crank" the steering wheel to make faster turns. [2] Brodie knobs were popular on trucks and tractors before the advent of power steering.

A steering ratio of x:y means that a turn of the steering wheel x degree(s) causes the wheel(s) to turn y degree(s). In most passenger cars , the ratio is between 12:1 and 20:1. For example, if one and a half turns of the steering wheel, 540 degrees, causes the inner & outer wheel to turn 35 and 30 degrees respectively, due to Ackermann ...
The steering wheel turns a pinion gear, which moves a rack back and forth to steer the wheels. This mechanism converts the circular motion of the steering wheel to linear motion, which is applied to the wheels of the car via tie rods and a steering knuckle. Rack and pinion steering has several advantages, such as a direct steering "feel".
Steer-by-wire without the use of a steering column was first offered in a production car with the Infiniti Q50 in 2013. [4] The system has a backup steering column separated from the steering wheel with a clutch. The clutch connects the steering wheel to the steering rack in case of failure of the electronic steering sensors or actuators. [2]
