called a wheel doesn't make it a wheel.
You just need to find some
catenary-surfaced roads and square wheels are
better than old circular ones. Lots of shapes go well with other road
shapes. We use circular wheels because flat roads are easier to make and
maintain than such roads. A little better explanation than that "it works".
