In Taiwan there are so many scooters that it would be impossible to have them park in the streets, so sidewalk parking is totally acceptable. Matter of fact, many sidewalks have designated areas pained on the sidewalk where scooters should park. Because of this, scooters often drive up on the sidewalks in the dips where we would expect wheelchairs and strollers to com up. Consequently, when in Taiwan, do not stand in the center of that dip. You might get run over as I almost did in one of my videos. :)
A few years back, the scooterists of New York City had some issues with paring on the sidewalk, so I dedicate this video to them.
