Here we make the following assumptions: 1. The smallest city size for a profitable operation is 50,000 2. The market potential is NYC is 80,000 drivers for a population of 8,622,698 3. The proportion of this number of drivers to population is the same across the US 4. The current ratio of Uber drivers in the US to the rest of the world is 1:3. We assume it's going to grow to 1:4
