The fact this information is finally out there is fantastic. But for God's sake, if this is the case:

“The existence of this sleek digital interface barely hints at the investment that had to be made in terms of hardware and infrastructure to make this enormous public benefit a reality,”

Why is this literally the worst app I've ever used? A weird old pixellated icon, non-retina bitmapped user interface elements, scrolling that doesn't continue and decelerate once you let go... not even any clear indication of which trains are uptown or downtown, no map to more easily pick a station, etc...

If they've been spending millions on the infrastructure to make this possible, couldn't they have spent more than what I would guess to be about $500 producing this app? It's like a third-grader wrote it. A bad third-grader.
