"For trips between (to and from) Manhattan and JFK International Airport, the flat fare is $52.00"
TO AND FROM
I know reading is hard.
I'm sorry that I missed that phrase. I don't have experience going to/from the one of three NY area airports that has flat taxi fares because I live in Brooklyn, not Manhattan (and Brooklyn applies to the analysis of Uber in NYC). There is definitely no need to be unkind to me about it; I'm sure you've misread something at least once.
As someone who does not live in Manhattan, I can say that I'm far more likely to be able to get an Uber than a taxi outside of Manhattan (although it's a little better now with the Green cabs). And, I've never had an Uber driver keep their doors locked and speed away at rush hour when I told them I was going to Brooklyn. My utilization of taxis in NYC is entirely different than my utilization of UberX.
