Interesting point, I'd believe it. I suspect the demographic that is driving instead of using public transit is quite small.
Driving for a commute isn't really possible in Manhattan unless the company provides parking. And those parking spots are reserved for executives. This group of people are price insensitive.
Passing through Manhattan can frequently save an hour of time in traffic elsewhere, those commuters will just see the fee as a higher toll.
All three major airports never tied directly to a subway, opting instead for airtran systems which create complexity and cost time. I suspect this causes a base level of traffic.
