Cars that get five hundred miles per gallon? According to this piece by LA Times editorialist Max Boot, it's possible using today's technology, including plug-in hybrids and "flexible fuel" vehicles that run on both petroleum and biofuels, such as ethanol and biodiesel.
Now, I'm inclined to agree with the editorial's main points: North America's petroleum dependence is a profound strategic and economic vulnerability; and we can make our transportation system much, much more fuel efficient using existing technologies--and without waiting decades for new technologies, such as hydrogen fuel cells, to catch on.
But what about this statement: "How to do better? Biking to work or taking the train isn't the answer. Even if Americans drive less, global oil demand will surge because of breakneck growth in India and China."
What on earth is he talking about?
