Is it possible that these could make roads obsolete? Now that is an interesting concept.

  Probably not because wheels are VERY efficient at transport across smooth level terrain, and a wheeled vehicle is less easy to destabilize than a legged vehicle. So when deciding between wheels vs. legs, it will be the usual sort of engineering tradeoff: which one offers the greatest advantage for your application?
