Maybe it depends on the cities but where I live, these scooters are limited to about 12.5 mph (20 km/h), and are supposed to share the space with bikes on the bike lanes and road, not on the sidewalk. So while they are indeed parked on the sidewalk everywhere, I do not see them as dangerous at all.
