The first book about Uber-X is an ebook by a driver. 

Makes sense.

An ebook written by an Uber-X driver who has driven more than 2000 trips.  This driver answers the questions that Uber-X riders have asked on a regular basis for more than a year.  The book tells the story of Uber-X’s genesis in a large metropolitan area from the point of view of an actual hands-on driver.

The book answers the What?, Why?, Who?, When?, Where? And How? questions that are on the
minds of literally millions of people around the world right now.
