My point exactly. And thinks about the reduced turning radius and diagonal
parking. I've seen a movie of a hmmwv with 4ws at www.amghummer.com, but
that seems to be a "2 steering wheels" implementation.
Now that some of the new GM trucks have 4WS, I would imagine there'd be some
newly-inspired interest in it.
