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?
