Unicyclist fined for riding on sidewalk

If Longboards are defined as pedestrians in Laguna Beach,  Unicycles are defined as bicycles in New York, the Segway Personal Transport (PT) remains undefined, then the body luge in Switzerland must be a Cushmann? Seems the Vehicle Code is wholly inadequate for defining personal transport and mixing it with high-speed automobile traffic. Reducing speed limits uniformly would improve compatibility and safety among all forms of mobility. Photo courtesy CBS New York article.
