So I think the big advantage of the subway system is that it is much faster in general. In less densely populated areas of New York the buses are a good (and necessary) alternative to the subway system since -as the author points out- the density of bus stops is much higher.
I used to know the tube map by heart, but I'm starting to forget - checking Google every time is faster and more reliable (since it takes into account e.g. engineering closures).
But I agree with this article 100%. If you live or travel a lot in NYC learn the bus system, it will only help you.
Nevertheless, interesting use of data.
