Utilizing the car2go program to satisfy vehicle-sharing option

I am working on a mixed-use residential project that has no parking other than street parking. The location is very centralized and to promote a car free lifestyle, the owner is offering tenants a break on the initiation fee for the car sharing program car2go. This program, which is active in a handful of US cities, allows access to 200+ Smart Cars which can be picked up and dropped off at any time or location by members. The car locations are found by logging into the car2go site on your computer or by using a smartphone app, these are both updated every couple of minutes. Since the cars being utilized by car2go are Smart Cars, it does not meet the required 8 person provision, but there is a likelihood of a number of available vehicles surrounding the project site at any one time. Has anyone used this or a similar car sharing program to meet the requirements of SSc4.3? If not, could it be a legitimate ID credit? Thanks very much!
