next speaker, please. >> brian hopper, brian noe, queena chen. >> mr. hopper, good morning. >> good morning. i think this is a good product, but only if it has teeth. i wheeled vehicles are constantly riding on the sidewalks, often at high rates of speed, and there are already laws on the books prohibiting these violations. i'm speaking of bicycles, skate boards, and often at a high rate of speed, often darting in and out of pedestrian traffic, and the only solution i see is you put more emphasis on citing people for all of these violations. now i think the scooter people probably feel entitled because they see this thing ignored. so i would say in closing, if you had a task force today, citing everybody riding their scooter skate board or bicycle on the sidewalk, i could probably, say this half jokingly, balance the budget of san francisco fore the year. thank you. >> thank you sir for taking the time to share that with us, we appreciate it. next speaker, please. >> brian noe, jerry depp, queena chen, nanny mcnally, andy blue. >> hi. my name is brian oh
