The residents of San Francisco are used to “disruptive” startups invading their city. Since 2008, Lyft, Uber and other ride-sharing services all arrived unannounced and local agencies responded with a mix of threats, “citizen arrests,” and eventually (with state legislators’ help) regulations. The latest intruders are electric scooters, scattered across sidewalks by the likes of LimeBike, Bird, Spin and others.

The city has learned its lesson.
