Girls At The Wheel

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 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 to move a hand away from the rim. A further development, the Rim Blow steering wheel, integrated the horn switch into the steering wheel rim itself.
