you could always just introduce an ethanol powered car. One that will only work on the shit. I mean like a 14 to 1 compression ratio. It won't be able to run on gas, but at least you can make it more efficient and get better mileage than running it in a gas engine with 8.5 to 1 ratio. But that would mean that manufactures would have to make a whole separate line of vehicles, and then the cost of the ethanol would just go up to the same as or more than gas anyway.
Bottom line, you are gonna pay more for less because they know you will. Whatever cheaper option they decide to bring to market, you will jump to buy it.
sorry, just full of hate as of late
