A me-too copycat startup like Spin who got kicked out of Seattle a year ago ( https://www.seattlebikeblog.com/2022/05/13/city-announces-ne... ) doing it this way doesn't seem like a great endorsement to me.
You have to spend $$$ up front on thousands of vehicles that cost hundreds of dollars each, and your marginal revenue per ride ain't great. Putting a dent in your vehicle theft rate becomes a big deal fast.
