but the scooters function in large part as as a replacement for cars. so it's replacing something with lots of problems with something with fewer problems. it's a net win. i do agree having regs to dissuade people from blocking & riding on the sidewalk with scooters seems very reasonable. once you have that i think scooters are basically problem free (except for maybe aesthetic concerns). even w/o that, i still don't see how anyone reasonable could think scooters were anywhere near the top of the list of hazards of sf streets. (perhaps they are a major inconvenience for wheelchair users?; i'd be interested in any first-hand accounts.)
