I would love to see it in more cities/countries, because I use it very often. I don’t have the money to buy one for myself so the best that happend was that the city decided a few years ago to make stations where you can rent these bikes for a short shopping trip or to some nice place. They aren’t even really expensive too.
Going by the repeated scooter fiascoes I’ve seen in downtown Dallas, I think these are trouble waiting to happen in any US city. We’re just not ready for anything nice that is also communal.
Many US cities have very successful bike share programs.
