What's the usual way to steer a large aircraft on taxiways? Do you rigorously keep the nose wheel on the yellow centerline, or do you oversteer? (I understand oversteering to mean that you steer outside of the line on turns in order to keep the aircraft as a whole closer to the center of the taxiway.) I've heard conflicting things about this and I'm trying to figure out how it is really done.
On the one hand, I've heard that pilots routinely oversteer large aircraft to keep the main wheels from drifting off the taxiway and/or to make sure that the aircraft is centered and the wingtips clear obstacles. But on the other hand, I've also heard that centerlines and taxiways are designed so that all aircraft can steer properly by just following the centerline with the nose wheel.
Adding to the confusion is a remark for KSFO that says "airline pilots shall strictly follow the painted nose gear lines and no oversteering adjustment is permitted." Why does this airport mention this restriction?
In cockpit videos I've seen, pilots seem to be following the centerline carefully, but I've seen only a handful of cockpit videos.
