Have you considered people don't like scooters in the city because it's another thing that's happening in SF where rich private companies decided to introduce changes without asking the people who lived there.

It's likely not entirely about the scooters themselves but what they represent and how the process has been implented. The city streets are funded by public money and the companies didn't treat residents with adequate respect or forethought before dumping scooters all over the city.

To me it is a physical manisfestation of startup culture and that's why many people hate them. Why consider the problems in advance, let's just do it and see what happens.
