Require ALL vehicles sold or manufactured in this country to get at LEAST 35MPG, not an average of 35MPG. We have the technology, we just have to force the greedy car-makers to use it. Once they stop building these ridiculously enormous, inefficient vehicles, the "demand" for them will evaporate, because it was an engineered "fashion statement" to begin with.
Add a "Miles per Gallon" test to emissions testing, which should also be Nationwide. It's easy to do - just calculate the amount of gas needed to run a 35MPG vehicle through the test, meter out that amount, & if the vehicle runs out of gas before the test is complete, the vehicle fails!
Impose a huge "Polluter Tax" on the sale of any vehicle (new or used) that cannot demonstrate 35MPG, and use those funds to develop a mass transit network that actually works, all day, every day, & is complete enough get you where you need to go.

Congress must take the reins to our country away from Big Oil, & the oil companies must bear financial responsibility for cleaning up the damage they have caused. We must pass tough laws with serious teeth for violations. Anyone who creates greenhouse gas should pay to offset the damage.
Don't even THINK about liquifying coal to burn in cars! We need to ban coal burning completely, which will end the need to destroy our mountains & forests & streams in order to mine coal, & force the coal mining companies to replant forests on the mountains they destroyed.
We must invest more in renewable energy than in blowing our "enemies" to bits. End all funding for military aggression immediately, give it to wind & solar energy development, & we will find we have less "enemies" to destroy.
