I would disagree with #2. Gas prices have little effect on commuting. The gas prices have not had a major effect on consumption. The larger factor is traffic in large metropolitan areas. Driving an hour each way is far more detrimental than an extra 5$. Biofuels have their place. They are not the magical pill that will wean America of middle eastern oil but they surely have their respectable percentage over time.
