Here's why:

The Auto Industry Is Backsliding on Global Warming.
Historic fuel-economy data reveals a disturbing trend -- every automaker’s average new vehicles emit more global warming gases today than ten years ago, with the exception of BMW.1 In 1999, US fuel economy overall dropped to its lowest value in 20 years. Two decades of fuel-saving technologies that could have helped curb CO2 emissions have instead gone into increasing vehicle weight and performance.

The Big 3 Account for Most Global-Warming Emissions from New Vehicles.
The Big 3 sell the dirtiest vehicles and capture the vast majority of US passenger vehicle sales, making them the worst polluters by any measure. Together, Daimler Chrysler, Ford, and General Motors’ vehicles are the source of 76 percent of the CO2 emitted by vehicles sold in 1998. Immediate action by these automakers to raise the fuel economy of their light trucks would significantly reduce global warming emissions from new automobiles.

It's not that GM doesn't have any hybrid products. It's that GM isn't building many of them.

Maybe Waxman can change this long pattern of avoiding their responsibility to the environment. But I don't see the Democrats trying to do much of that the past two years in power. It's not like this "crisis" is new:

During the Clinton administration, the government offered the big three automakers, Daimler-Chrysler, Ford and General Motors, incentives to develop energy-efficient cars, but the carmakers arrogantly ignored efficient solutions and developed even larger and thirstier automobiles. Seemingly, GM missed the memo that oil is neither plentiful nor cheap in 2003 when it introduced the 10-mpg Hummer.

I surely earned the monicker "Stupid Git" on this post. :)

We all make mistakes...except me of course, I thought I made a mistake once, but I was wrong. ;)
