“Limited urban street and sidewalk space play a role as well,” writes David Zipper of antipathy toward “e-scooters”, and setting aside opposition by car people I think this actually might be the primary motivator. City sidewalks are becoming increasingly crowded even as cities move too slowly to give either more room or more consideration to giving over more space to transit modes other than the automobile. Pedestrians, bicycles, skateboards, bike-rental docks, and now scooters both in use and haphazardly parked suddenly all must share what limited sidewalk space there is, while cars continue their near-monopoly on city streets. Whenever infrastructure week finally arrives, let’s expand sidewalk space before we add any more transit modes.
