"The median household income of those with wheels is more than double that of those without - $85,000 compared with $40,630." [1]
Do you really think someone who is "poor" can afford "UP TO 12 HOURS $31.25" [2] daily parking, when an unlimited Metrocard is $32 weekly? The commute would be shorter in the car, but with $150/week for parking, add tolls and the cost of insuring/maintaining a car, I do not see congestion pricing being a poor tax.

The majority of New Yorkers — and a supermajority of Manhattanites — do not own a car. Those who do own cars have incomes nearly twice as high as those who don't. Only 5.8% of commuters to Manhattan arrive by single-occupancy vehicle.
