Swing-away steering wheel Introduced on the 1961 Ford Thunderbird, and made available on other Ford products throughout the 1960s, the Swing-away steering wheel allowed the steering wheel to move to the right when the transmission selector was in Park, so as to make driver exit and entry easier. Tilt-away steering wheel Introduced by Ford in 1967 after updates to Federal Motor Vehicle Safety Standards requirements. Though it was an update to the swing-away steering wheel, which did not meet updated safety standards, it offers limited movement but added convenience due to the automatic pop-over function over its predecessor. Quick release hub steering wheel Some steering wheels can be mounted on a detachable hub a.k.a. a quick-release hub. The steering wheel can then be removed without the use of tools, simply by pressing a button. The system is much used in narrow-spaced racing cars, to facilitate the driver getting in and out, and in other cars as well, as an anti-theft device.

As a rule, the wrist should not be bent, but must be kept straight to avoid overexertion of such tissues like tendons and tendon sheaths and compression of nerves and blood vessels." The act of turning the steering wheel while the vehicle is stationary is called dry steering. It is generally advised to avoid dry steering as it puts a strain on the steering mechanism and causes undue wear of the tires. Buttons and controls on the steering wheel The first button added to the steering wheel was a switch to activate the car's electric horn. Traditionally located on the steering wheel hub or center pad, the horn switch was sometimes placed on the spokes or activated via a decorative horn ring which obviated the necessity
