IMO the e-scooter app + sharing model solved the parking and storage problem in a way that Segway did not. You don't need a bike room at work or secure bike parking at the restaurant / movie theater / bar if you can park it anywhere and get a different one to ride home. Also allows one-way trips where you use another mode of transport to get home.

Downside: you might not have immediate availability, but you can always walk a block or two to find another scooter.
