It's really too bad Bloomberg's plan appears to be dead, at least for now. The fact is, New York is basically impassible at certain times of the day and a lot of the people driving into the city are people who could almost as easily have taken mass transit. The claim that the $8 would be some kind of poor tax is ridiculous. You'd have to search pretty hard to find a poor person who drives into Manhattan every day alone in their car to work.
Besides, for anyone who cares about New York City and specifically mid and lower Manhattan, remaining a viable place to live, easing the congestion and the pollution should be a priority. Bloomy's right...far be it for Albany to understand anything beyond their own narrow self interest.
