The main advantage is that you can combine them with public transportation: you take a dockless bike to an underground/bus station, then once you get off you take another dockless bike to the destination, which effectively gives you very cheap and very fast transportation from anywhere to anywhere. The other advantages are not having to worry about theft, being able to get a bike wherever you are even if you didn't anticipate it, and being able to get somewhere by bike and go back in a car with someone else or vice versa.
