In West Oakland I see many people using the Ford Bikes, but yet even more people using the Lime scooters. Kids, adults, techies, non-techies. I think they look kind of dorky, and some end up on the sidewalk and dumped in Lake Merritt. On the other hand, it appears that people are using these scooters a lot, possibly instead of driving. That seems like a positive outcome to me.
It would be good if more safety concerns were met though - I do think mandating helmet usage is a good thing.
