Car2Go works here that you don't have to leave or pick them up from designated spots -- they have an agreement with each city to allow general parking, even in neighborhood zones. Not sure if it was the same in your city, I'm used to ZipCars having special spots which is a little less convenient. It's a good alternative to public transport when you need to cross a city and transfers would be annoying.
