I think the general idea initially was to change how the company is described wholesale, including in the lead, to a "taxi dispatch service" from a "ridesharing service".  There doesn't appear to be consensus for this because most RS do not describe Uber that way.  
Based on our discussion so far, what I'm suggesting is that 
we leave the lead alone and maintain the "ridesharing service" description, and 
 under the 2012-present section of History, that we describe that Uber implemented an option in their app  called Uber Taxi that dispatches actual taxis drivers to customers, and that it has been implemented in multiple cities.   
So, if folks want to support or oppose that idea, please indicate that below so we can start gathering a consensus on the matter.   drop me a line
