You know I am not well informed on the finer details of the traditional taxi business...but a couple of things: * Taxi companies don't portray themselves as "marketplaces" for regulatory purposes. * Taxi rates are publicly displayed and known prior to rider entering service agreement with cabbie. * If you are correct, then rates aren't sent by cab companies but a regulatory, unlike Uber who sets the pricing dynamically. Although I want to reaffirm that I am generally a supporter of Uber and similar ride services, I just don't see them as marketplaces.
