While not vehicles to ride, Theo Jansen's Strandbeast creatures/vehicles are able to walk only using the wind and wind powered pneumatics. His animated works are an incredible fusion of art and engineering and eventually Jansen wants to put his "animals" out in herds beaches, so they will live their own lives in peace.

Perhaps in the far, far future humanity's predecessors will learn to tame the gentle Strandbeast and the cycle will begin all over again.
