It doesn't even require a particularly long commute to get to that cost. Some back of the envelope calculations: The IRS has to conduct an annual study of the average cost of operating a vehicle, to set the mileage reimbursement rate for cars driven for business purposes. They currently estimate it at $0.56/mile (including depreciation, insurance, registration, gas, maintenance, etc.). So $9k/yr is 16,000 miles/year. The average U.S. household has 1.9 cars, so that's 8500 miles per car. If you commute 250 days a year, that's only a 17-mile commute each way, which is not coincidentally just about the U.S. average.
