Another perspective, from a skateboarder: In New York skateboarders are banned from sidewalks and have to skate in traffic. I've got a solid push and hold my own among bikes and cars but, regardless, get all kinds of flack from drivers. When I take the to sidewalk due to dangerous road conditions pedestrians are simply far too unpredictable, scared, and oblivious to permit me on board so I reluctantly walk. You know who I never see walking when they're on the sidewalk? Scooter riders, electronic and otherwise.
