I would like to purchase a high-mileage / low-emissions vehicle which I can drive (alone) in the carpool lanes around the Bay Area. Hybrids present one option, though I'd rather be in a diesel VW Golf, running biodiesel. I need help figuring out the requirements listed here to see if a diesel Golf meets them. And does anyone know if filling it with biodiesel changes anything? What other vehicle options are there?

I've been interested in the growing chatter about biodiesel. Some friends raised an interesting question, though: peanut allergies are increasingly common and are increasingly lethal. Soybean allergies, although less common, still exist. Will biodiesel emissions from peanut or soybean oil cause negative reactions (like, well, death) in people with severe allergies? If so, what type of regulation on biodiesel is likely?

Fuel Filter? Has anybody had long-term experience using North American bio-diesel in a TDI? My dealership is dead-set against it, but my European friends swear by it. (I tend to distrust my VW dealer, but I don't want to be cavalier) Since I live in a moderately cold climate, I would only be using it in summer.
