Living in SF these days and up until a week ago I thought the same way. I serendipitously had an opportunity to try a Bird electric scooter. I was heading to a meeting a few blocks away and one happened to be parked outside of the building I was leaving. It was far enough that I would have normally used Uber to get there but not far enough that I couldn't have walked if I didn't have to rush over. Long story short, I grabbed the App, started the scooter, and really enjoyed the ride over. It cost a fraction of the Uber ride and got me there faster.
I've been seeing these scooters popping up all over SF including Lime and Spin branded ones.
I hope to see more of them spring up as a viable alternative to using a car to get everywhere. Though I see the lack of helmets being included with these as a disaster waiting to happen.
