Following the stimulus package, this piece in a Slate publication called "Big Money" does a good job at showing how the stimulus transportaion funds follow the status quo of federal transit funds that virtually fund exclusively the expansion of highways over public transportation.  It's titled, "Potholes in the Stimulus Plan - Why isn’t mass transit part of the package?" by Amy Tennery.  

"Despite President Obama's vaunted green initiatives
and efforts to provide tax relief to low- and middle-income families,
stimulus funding for transit contradicts both these goals. The package
provides little to no incentive for mass transit projects that would
reduce gas consumption and assist non-auto commuters."

She also talked about Los Angeles and how the stimulus package was going to shake down:

"Los Angeles, with its infamous traffic problem, boasts one of the nation's most costly transit systems, Metrolink, which recoups just 45 percent of its operating budget from fares and mostly serves surrounding suburban communities like the Inland Valley and Orange County.

"The stimulus package did not break from that tradition," said
Manuel Criollo, lead organizer with the Bus Riders Union of greater Los
Angeles. "The drive is to construct and not to operate."

Perhaps it's time to visit that used-car dealership?"
