How does that work? You don't swipe your card going out. So, if you get on the system in, say, Brooklyn and get off at 63 and Lex, how does it know not to charge you when you go in again at 59th and Lex? All your card shows is an entry in Brooklyn and another entry at 59th and Lex.
I was wondering the same thing, but thought it might have just been b/c I read the post fast.
