These things have suddenly appeared all over downtown DC, along with the pastel-colored dockless bikeshares (LimeBike, OfO, et al). I tried a Bird scooter—they can go fast! But it takes nerves of steel to ride in traffic. The drivers don’t like it when you take up a lane, even if you ride fast. But if you go on the sidewalk, the pedestrians get mad at you, for good reason. I think they are a great idea, especially since both the NY subways and the DC Metro are both in a state of collapse. (I use Capital Bikeshare, a system that requires docs, every day in my commute. The bikes are sturdy, a bit heavy, but well-suited for urban travel.)
