The 8880 Supercar has all-wheel steering so that both rear wheels turn less than
the front ones. That's not quite the same as Ackerman correction, but it helps.
I've seen Ackerman steering correction done in LEGO, but of course I can't find
it now that I'm trying to look for it specifically. It might have been in one of
those older "building robots using LEGO and the RCX"-type books.
