Anonymized Ride Share Data, where does it go?

Washington Post points out that local regulations on ride share continuously forego obtianing access to anonymized ride share data. Its the same data local governments collect from taxicab drivers. 

The data  serves two purposes.

(1) It strengthens transportation systems  and gives tools for transportation planners, and

(2)It  provides an understadning of how many jobs ride share is creating. [Washington Post]
