At every occurrence of the term “steering wheel,” we have substituted the term “steering control.” These terms are synonymous as can be seen by the definition of “steering control system.” Nonetheless, the agency believes there is some merit in changing “wheel” to “control” in consideration of steering controls that may not be circular, e.g., shaped more like an air plane yoke control. We note that such systems would have both a “hub” about which they turn and a rim, i.e., an outer edge. A similar change was made in every FMVSS that is the subject of this NPRM.
