The subsidies ended awhile ago and prices for E85 didn't "rocket up" like people claimed during that debacle.
Plenty of cars can be augmented to accommodate ethanol without too much trouble. And that small amount won't make a big difference. Go look at people building E85 turbo cars. A lot of camaros/vettes using stock fuel tanks with line that can handle ethanol and a good tune. Not a big deal.
With our options, ethanol will be the future. Once algae fuel is sorted, it will easily become the new standard. Why fight it?
