A steering input device for a steer-by-wire system is provided. The input device comprises a first shaft and a hand wheel. The first shaft is rotatably installed in a first housing. The hand wheel is connected to the first shaft such that the hand wheel and the first shaft drive one another. The hand wheel has a range of motion of between about ±45 degrees and about ±90 degrees. The hand wheel also has an outer dimension of about 12 inches. The range of motion and the outer dimension allow the steering input device to be installed in a vehicle in a non-conventional position relative to a twentieth century conventional position including at least one of the hand wheel extending from the first shaft extending along a length defining the vehicle on one of two sides thereof and the hand weel extending rearward in the vehicle farther than an instrument panel.
