It's too darn bad we can't just stop subsidizing ethanol...if we did, the price would be prohibitive and demand would drive the reversion to "regular" gasoline. I understand this is a complex issue with multiple parties involved, but if there are tax dollars used to artificially hold down the cost of the fuel, I'd greatly prefer the same dollars just be given to the growers and producers directly...perhaps as an incentive NOT to produce.
I guess I look at it this way...if ethanol was such a great fuel, by demand there would be far more vehicles that use pure ethanol than there are now. In a free market, consumers (by the wisdom of the masses) choose the best product. In a subsidized market, those forces are stunted and the natural evolution and progression of products are forcefully directed, quite usually toward a less favorable outcome.
Cork in mouth...rant over. Sry.
