Wheels and legs solve different problems. Wheels aren’t very useful without perfectly smooth surfaces to run them on. If roads were a natural phenomenon that had existed millions of years ago, then isn’t it plausible that some animals might have evolved wheels to move around faster and more efficiently?

GP was stating that "two cameras mounted 15cm apart on a swivel slightly left of the vehicle center of geometry" has proven to be a _sufficient_ solution, not necessarily the best solution.
