My biggest issue with scooters is that the sidewalks on most streets in North America are way too narrow to safely use them while others are walking, and we’re seriously lacking in dedicated bike lanes. Both of which are issues with the prioritization of car infrastructure over all else as opposed to problems with scooters themselves. Since scooters cannot safely run on the road but is still too fast for exclusively pedestrian paths. Where there are dedicated bike lanes in my city, scooters share them with bikes perfectly fine.
