My friend's mother works for the department of energy. She was saying that they could develop a sport utility that gets around 50 MPG without sacrificing overall performance. She also said they would not do that though because it would make every single car out there obsolete and would ruin the economy as a whole. That it would have to be phased in over many years. Is this true? Maybe I did not listen in Econ enough in college, but why would the introduction of such a valuable product ruin the economy. Are oil companies that in control of the American economy? My gas prices are around $1.75, and I've never seen it this high. The prices are ridiculous now. If they can make that kind of fuel-efficient cars, why in the hell wouldn't they do it? And what is going to be done about current gas prices?
