Car2go typically operates on a spontaneous, first-come, first-served basis, meaning that reservations for vehicles in advance are not standard practice. Users generally find available cars through the Car2go app or website at their desired time. However, it is important to check the specific terms and conditions, as well as any recent updates, as circumstances can change over time. Car2go may introduce features or options that allow for different methods of access. Therefore, it is advisable to refer to the current information on the Car2go website or app for more details about vehicle availability and any potential reservation features that may be offered. Users can stay informed about these services through frequent checks on the official platform.
