Interesting discussion so far......here are some thoughts on the bigger picture.
So The Automobile is what, 100 years old ? and I've read that many scientists believe we have used up close to, if not more of the worlds fossil fuel in that brief amount of time, demand continues to grow,much due to India and China's growing thirst for oil, and supply continues to shrink. Folks, the prices for this scarce resource aren't going to go down, rather they will continue go up.
I hope the next president has the balls ( sorry Hillary

) to lead us through the tough years to come by creation of what is sure to be an unpopular national energy policy. Including ADDITIONAL taxes on Fuel, the proceeds going to help subsidize The prices faced by Truckers, which would help control overall inflation of prices. He'll need to appeal to the public to make sacrifices in their quality of life to help us reduce consumption until REAL alternatives to Fossil Fuels are in place......I'd also like to see taxation of the oil companies directly tied to the amount of resources ( ie record profits ) devoted to development of alternate energy sources. Also cutting a similar deal with the auto industry to deliver vehicles that dont depend on fossil fuels. The President should tie all of this to a timetable similar to what JFK did with putting a man on the moon.
Sadly, I fear none of the candidates have any intention of really dealing with this problem......the person who had a great opportunity to do so ( GWB ) Iin his 2nd term was more interested in his war than in taking a courageous stand and get us started down the difficult path that lies ahead.
Imagine the impact of the US reducing its consumption by 20 percent on the marketplace. It would require the turning down of thermostadts in the winter, more efficient vehicles that get 50 percent more miles to the gallon or dont rely on fossil fuels at all, expansion of mass transit alternatives, etc.
In the past, the american people made amazing sacrifices for the good of the country ( like rationing of resources in WWII) I think we all need to change our beliefs that we are entitled to a completely cushy life to help insure that the US remains a superpower in the decades to come.
