There's no situation in which the NYC subway can accommodate a 50% increase in riders. Just building housing isn't enough. I do think this article is right about a lot of things, but I think that if we could magically increase housing, we would find what NYC found building highways: building them actually created traffic, and they could never catch it. If a city's infrastructure can't dramatically increase, the city's full. New York would need to double transit infrastructure to make current use comfortable.
