I can understand the desire to cut the sugar tarrif, but I don't think corn as a fuel is rediculous. Maybe some other crop could work better, but corn does work.
As I mentioned, the main attraction (for me anyway) is that it has a low cost of entry. The conversion of a current car to a biodiesel car cost ~$100 and labor. A *new* car using fuel cells or electric costs several thousand. People on a fixed income will never buy those cars because it would cost half of what they make in a year, and they kinda need that money to feed their kids.
Pie in the sky is nice, but nobody who makes $30K a year is going to be able to drop $20K on a brand new car. This is something that has to be taken into account if you want to radically change the way we drive.
