The Philadelphia Parking Authority is working to keep uberX illegal in Philadelphia, according to emails uncovered by the Philadelphia Daily News.
The news is at odds with the PPA’s messaging when uberX went rogue and launched in Philadelphia in the fall of 2014. From our story:

The Daily News reporter who filed the story, William Bender, took note:
