Thank you for the interesting video. We have a similar problem in Milan, Italy (www.ilgiorno.it/milano/cronaca/monopattini-sharing-1.4741626), where the public authority has forbidden the use of push scooters (Italian:"monopattino"), because there isn't yet a clear and universal set of rules and limitations. Does California provide a mandatory personal protective equipment helmet, any speed limitation and/or an exclusive transite on bike lanes, as it seems to be at minute 1:25??
