Rudder pedals on Transports are not connected to the nose wheel, as they are on small aircraft. For example the rudders pedals on an Airbus A320 can move the nose wheel 6 degrees. in comparison, the tiller can move the nose wheel 97 degrees. The exact number of degrees varies with groundspeed. Taxiing a transport close to obstacles by rudder pedals alone is not possible. If you are unfamiliar with transports, use of wheel brakes to steer is for the most part useless as well. If the tiller is inop, you have to be towed.
SOP says to remain in your current seat until after landing. After landing change seats only if necessary to taxi. In the case of the Airbus, the copilot can remain in their seat to the gate. There is a tiller on both sides. B-737 copilots must change seats to operate the tiller.
