Share a Car Program in Copenhagen

I used to hear Rent a Car program or business anywhere.  However in Denmark they have this "Share a Car"  Ya, the program still intended to those who are looking for car specially in Copenhagen.  You can view a video tips at "Everyday Life" segments to this link MyDenmarkTV.com.

Does anyone here has the experience how is it like to go to a "Share a car" program? Maybe you can share it here how is it like availing such kind of services.  And how does it differ with a Rent a Car program?

Thanks
