It's a shame they are being banned in many places, because they are such a great idea. It's the equivalent to a taxi, but a small fraction of the price. It's such a great utility to be able to pick one up and go directly to your destination. All the advantages of having a bike, but without most of the downsides. People just needed to be somewhat polite and disciplined - too many ride fast on sidewalks, leave them in…
What exactly are the downsides of owning a bike that you don't have owning a e-scooter?
The main advantage is having it where you need it - maybe you got the metro or the bus to work and now you want to go on somewhere else. Your bike is at home. Then you want to head to a friends house, but there is nowhere safe to leave your bike but you'd be happy to leave the rental scooter outside, then two other friends want to join you on a trip to a pub, this time you have your bike but they don't, so you cycle alone and they get a cab.
I love cycling, but scooters (rental and private) def have some advantages
