Congestion Pricing for DC?

A little-noticed provision in the budget that Bush sent to Congress provides for $130 million to be allocated to "congestion pricing" schemes, which charge drivers a fee to drive into city centers. From the WSJ [subscription only]:

the centerpiece of the traffic plan involves an initiative that some critics say amounts to a tax, a plan depicted by administration officials as "congestion pricing." The administration will award $130 million in grants starting this spring to help cities and states build electronic toll systems that would charge drivers fees for traveling in and out of big cities during peak traffic times. The money also could go to other congestion strategies such as expanded telecommuting, but administration officials make it clear they think congestion pricing is the most powerful tool they have. The White House will seek an additional $175 million for congestion initiatives in next year's budget.

DC, of course, will gobble up this federal money and try to introduce a congestion pricing scheme of their own. The Wa Post op-ed says that the price will be $1, but the London price, which is the only actual experience of this practice, is 9 pounds per day, which equals about $18 US dollars.
