If the small scooters are (allowed to) drive 20 ... 25 ... 30 km/h, public transportation becomes largely uninteresting in large cities and in inner downtown of cities for distances up to 10 km, especially since the small scooters do not know any parking problems.
Similar to scooter sharing, car sharing is operated for travel over land, i.e., over longer distances, in which the cars run silently electrically, and can be operated permanently thanks to zero poinz energy from motionless converters with unlimited range, because they never have to go to a charging station.
Of course, anyone who wants to can keep his or her vehicles privately owned, can do so. However, for cost reasons, the majority of people will probably opt for an interconnected network of individual public vehicles; that is, vehicle ownership is in the hands of the community, and the respective use is made individually as needed in the sense of individual transport. A mixed mode is also conceivable, where the vehicles for the longer distances are owned by the community, but the smaller vehicles for the shorter distances (such as scooters) remain in private ownership.
