How car rental companies move their cars from one location to another?

qadata: How car rental companies move their cars from one location to another?
I am working on an application and need to understand how car rental companies move their cars from one location to another when there are too many cars left by customers at one location. One way is to give dirt cheap one way rental offers to customers originating some specific location. However, I am trying to understand do they use auto transport companies to do this for them? If yes how much business auto transporters get one average from such scenarios?

Also, do car rental companies have some sort of contracts with auto transporters saying they will move rental cars always or on demand basis?

Thanks for your time!

Wut about those trucks that carry cars around?

They gather up the employees, one to a car, and one in the shuttle to bring em back.

Their own employees move them around within a limited area. Long distance they may offer reduced/free rental. To get on their list of approved drivers you must have a perfectly clean driving record. They usually already have “regulars” to transport the cars. Northerners going south for the winter or north in the spring for example.
