Good. I was nearly hit numerous times by riders on the sidewalks here in SF. They provided something easy for people to get around, but in the end people were reckless with them. I myself had several close calls riding on the janky streets of SF.
(Why are we holding scooters to a higher standard than the utter madhouse that I see on the roads on a daily basis?)

Why do you only hold the vendor responsible for what happens on the sidewalk? Is it some kind of sacred space? Why do we just accept that people will behave like savages on the road running parallel to it?
I'd say never. Because they successfully lobbied against it and shaped public perception way back.
They used to be blamed for it. They just acquired and spent enough money to make it disappear permanently.
