During the first internet boom, the founders of a startup I advised gave me a gas-powered, stand-up scooter after I complained about parking near their office. The first time I rode it, I got pulled over by a police officer. He said, “We really don’t have any specifics laws about what you’re riding, but it just seems wrong.” A couple decades later, those scooters (now electric) have appeared everywhere in San Francisco. And we still don’t really have any applicable laws.
