The steering wheel was introduced to the automobile market in 1899 by Packard to replace the tiller. The steering wheel controls the movements of the steering system through rack and pinion steering, power steering, or computer controlled steering. The basic function is the same today as the original design--that is, controlling the direction of the vehicle. The appearance, along with additional features, has changed through the years.

The steering wheel has become the location of convenience for many actions such as the horn, cruise control, and radio controls. Having these controls accessible on the steering wheel reduces the need for the driver to take his hands off the wheel. Heated steering wheels enhance driving comfort in extreme winter conditions. In addition, an airbag is located in the center of the steering wheel to protect the driver in the event of an accident.

Another great convenience of modern steering wheels is the option to include a tilt feature. This feature allows the steering wheel to be raised or lowered for the convenience of entering, exiting, and driving the vehicle. Some steering wheels are equipped with the option of telescoping--moving closer or further away from the driver.

Steering wheel covers are often purchased to increase the grip or for added comfort when many hours of driving are needed. Some drivers--particularly truckers or people with disabilities--opt to purchase a brodie knob to make driving long distances less tiring. This knob attaches to the steering wheel and swivels which makes driving with one hand less difficult.
