Sure but most families need a car anyway, and once you have one the costs of ownership, maintenance, insurance etc. are irrelevant to the costs of individual trips.
But even then we have to consider marginal costs. Owning one car is better than two or three. Here in Texas, it's not uncommon to see households with 4 or 5 cars.
That's expensive.
Either way it's close, and the closer you get to Manhattan the higher that number goes. Remember, there are over 8 million people in NYC, and over 12 million during the work day.
Many components degrade simply due to time, especially things like rubber seals.
