On a Friday night in New York City, pizza deliverers are busy, and this Food Machine episode from the PBS series 'America Revealed' visually shows the routes.
The video shows a bird's eye view of Manhattan, which is illuminated by bright, golden lights. The squiggling blue lines are the pizza delivery routes on an average weekend night. It's not the same, say, as if Google Street View did this because the vantage point of a satellite shows the drastic routes pizza deliverers take.
PBS goes on to show not just the the deliveries in Manhattan, but also the routes truckers take to deliver products to pizza joints. These routes are highlighted in red and can be seen traveling all over the northeastern states of the United States. This amazing GPS tracking from the Food Machine episode is the other side of the story when it comes to pizza delivery.
