“Car-sharing program” means a program by which an entity offers the use of motor vehicles to its members and patrons on a 24-hours-a-day, 7-days-a-week basis, charging for the use of these vehicles on a time-used basis. Impounding areas include those locations on the streets, on public-metered parking lots, and in City-owned parking facilities that the Director of Transportation reserves for parking vehicles used in a car-sharing program approved by the Director.
