Uber sentences to ponder

Uber seems to be moving to a system where some rides cost more than others, even in the absence of surge pricing:

An Uber spokesperson assured Axios that pricing has nothing to do with a rider’s perceived level of income, past rides, or any individual characteristics.

So far only for UberPool in limited locations, I also am interested in this as a test of whether social media can strike down price discrimination.  What will the prices be contingent upon?  Traveling to a starred Michelin restaurant?  Why then use UberPool?  Here is further (but still incomplete) information, and yet more here.  How long will it take people to figure out the implied rules for contingent prices?  Are we these days capable of accepting any such rules as fair?

The pointer is from Matthew Kahn.
