The city of Boston plans to introduce a Paris style bicycle rental program. I have serious doubts that will work, mostly because of the mindset of Americans.
First, I don't think many people will use the program because of course the car is sacred and revered, bicycle riding is for losers. Second, vandalism and theft are unfortunately endemic in our big cities. Those bikes will last about three seconds.
It's a great idea and I hope it works, but I have serious doubts.
