Because ZipCar owns the cars, they're able to take stronger precautions to track and to prevent theft. HiGear's model opened a wide range of attacks against the customer cars, some of them hard to tie to HiGear. I wouldn't be surprised if the total theft from HiGear is more than 4 cars, but that some of the other thefts either haven't happened yet, or weren't easily tied to the HiGear service.
