Lots of traffic problems in major cities due to giving Uber unlimited public resource capacity, rather than using the free market to bid it out (which is what medallions are, if I understand correctly).
Did the world blow up? Is that our standard for success? The world of many medallion owners blew up because Uber bought off government and propagandized the public to give them for free what others have to pay for.
