One of the things worse than burning petroleum in cars is burning corn ethanol in cars. It has essentially all of the downside, only amplified through energy inefficiency and politics.
If I had any political power, I'd end the ethanol subsidies. That would be the simplest change to save ~$20b or so ($6b in direct costs, higher corn prices, corn subsidies, use of fossil water and other limited resources, less fuel efficiency)
