Noah Kazis writes, "The $19 billion number is a quick, conservative estimate that almost surely understates the savings New Yorkers reap by not driving. The study estimates that, per capita, New Yorkers drive nine miles per day. It then multiplies that figure by the national average cost of operating a vehicle, 40 cents per mile. Compare that total -- how much New Yorkers spend on driving, per capita -- to the national average, and you get $19 billion in savings."
