They need to know where the scooters are but they don't really need to know where the customers are though. Consider a similar system that would work with coin operated scooters. They can have GPS in the vehicle without constant association with users. In any cases these two tracking databases, where is each scooter and who is on which scooter, should be separate so they can provide the former to law enforcement without disclosing citizens whereabouts.
