With 400 cars scattered across the city, you can almost expect and plan for a car to be available in your vicinity. Huge flexibility and so many use cases.
Owning a car in Copenhagen, even a small and highly economical car is easily minimum 400 USD per month, everything included; parking, depreciation, fuel, insurance, service etc. You can drive one of these guys around for many many hours for the same price. So if you live in the city and don't need a car for the daily commute, this is a superb alternative to owning one. Have already signed up and expect to use this on a regular basis.
