   The programming is extremely challenging.  Otherwise walking and   
   hopping have some nice improvements over rolling.  Imagine going down   
   the highway and your car has the option to hop over someone instead of   
   ramming into them.  Imagine if a pothole was nothing, and it took a   
   2-3 foot ditch before you got even close to worrying about it.   
      
   But again, the programming is tough.  Insects are much better at   
   walking and hopping than computers, these days.
