I think what he's saying is that most car wheel hubs are designed so that
the centre of pivot for the wheel is around where the centre of the diameter
of the hub would be or very close to it.
Nearly all car and truck wheels have an offset so that the turning axis of
the wheel is centred such that the turning radius of the wheel is in line
with where the wheels are pointed, and not off to one side, which would make
the turn unbalanced and have the car lose traction/turning force. LEGO
wheels, however, are not designed with this in mind. I have not seen any
LEGO hubs specifically designed to the same tolerances as real-life hubs or
the same turning pivots as real-life hubs.
This may be due to the limitations of plastic injection molding and what is
best for strong plastic wheel hubs.
There are probably some older real-life wheel hubs which would not be
centred properly, however, most modern cars would have properly centred
wheel hubs so that the steering forces are transmitted correctly.

If I'm interpreting right, I think what you are talking about is a way to make things so that if the wheels are turned in a stationary vehicle, there is no force to move the front end of the vehicle. The wheels turn around the spot where the (...) (16 years ago, 19-Jan-08, to lugnet.technic)
