I consistently see people zooming down the sidewalks on scooters because: they fit, they accelerate quickly, and they are often too slow to be in the bike lane. Personally I think this was the massive failure by these scooter companies. No one is riding them in the streets. They are on the sidewalk going 10+mph. I really don’t think people would be quite as upset if they weren’t constantly dodging scooters going down the sidewalk.
