Uber entered both markets. I live in Manhattan(UWS) and treat taxis or Ubers as interchangable. When you can pull up an app on your phone and have a car in 2 minutes, that is effectively similar to a street hail. Heck, because I work near Chelsea market(big tourist destination), using Uber gets me a car 5-10 mins quicker than trying to hail a cab and constantly getting sniped by people who appear upstream.
