The amount of land used and traffic problems caused by these scooters is nothing compared to how much public space is dedicated to moving and storing cars for personal use and is a actually a massive improvement. Additionally, if you've seen their actual use patterns in cities like Washington D.C., because of their dock-less nature and ease-of-payment they are being used by lower-income populations that don't use bike share or other similarly centrally planned options.
Scooters are hugely benign civil disobedience that are helping with what is probably the biggest problems in the world: pollution from personal transportation, whether carbon or localized exhaust. I am cheering them on completely and hope to see more similar disruptions that help the world and make investors rich.
