according to that map (and common sense) basically everything in New York is a 10 min walk from the subway even if it isn't a pizzaria.
What a lot of people don't realize is that the subway is not all that convenient to where large parts of the population in the city lives and a lot of people take busses (or a combination of a bus & a train) to get where they need to go.
Edit: a version of the map I posted is in the article.

Um, how many people actually live in those islands you found? A lot of those narrow islands could be eliminated by just increasing the walk time to ~12 min. Even more should be covered by the recent 2nd ave extension. The whole strip on Manhattan's East side will be covered once the 2nd Ave line is finished. No one lives in Newton Creek. Many of the other transit dead zones are functionally low rise suburbs. I wouldn't be surprised if the population on those islands you found is dwarfed by NYC population overall.
They also attempted to predict the likelyhood of availability of toppings, based on neighborhood features.
A little unknown fact is Water quality makes a difference on the taste of pizza. There is a saying in the states that you cant replicate true new york pizza unless you use new york water, etc.
Good pizza water tastes awful if you drank it as is. I dont recall which elements were added inside of it, but its there. Another interesting tidbit is pizza quality is sometimes compared to coffee quality for water enthusiasts.
Sometimes called "waves". A first wave coffee shop is like getting a awful espresso shot at a hotel. 2nd and 3rd wave is like starbucks. 4th wave is when a coffee shop sources their own products and knows the history behind its goods. 5th wave is everything - these are generallly operated by famous baristas who have basic chemistry knowledge and expertise operating a espresso machine.
Pizza is the similar in ratings to coffee in this regard.
Baseball and politics are the safe topics. An article about pizza and subways ... say far away.
If you go to a lot of college towns you can get a pizza topped with taco ingredients, or fried chicken and bleu cheese, or even pesto sauce and cheese-filled tortellini.
It is not far fetched that Italian Pizza could be a candidate for a TSG marking. There are individual pizzas which already are protected, take Pizza Napoletana for example.
(Ok, I take that back, In-n-Out Burger is more overrated than both.)
