I am not sure that this clarifies anything. My point was that steering is
entirely irrelevant to the question. A vehicle entirely without steering
(say, a 4-wheel trailer) under braking, suffering a brake failure on one
side, will pull strongly to the other side. This effect has nothing to do
with "inboard steering centers"; conversely, steering geometry cannot in any
way counteract this tendency.
