I apologize if I phrased the question in a way that discounted the great stuff that is being done. What I was trying to get at is that when we talk about mileage, it seems that the focus is always on trying to have hybrid vehicles or electric power.
Are there not ways we can find efficiency in terms of our mileage, our fuel economy, with gasoline power? Is there research being done in that specific area? Is there hope that gasoline engines can meet the challenges we're looking at alternative fuels for?
