The only problem with mass transit is cost. If you live on Long island and travel to the city it can cost $350 a month just to get to work. It's closer to $400 if you're in CT.
I know a couple of guys out here that make their own Bio D...they all swear by it.
i was just stating the mass transit as one way to deal with it, i live in an area that doesnt have it, nor would it be practical for this city to have it.
there is absolutely nothing wrong with biodiesel. very simple chemistry, only safety concern is when you are mixing/handleing the methanol and the lye. very clean, better for your engine, makes ur engine run quieter, and helps the US economy, not the middle east. only downside, YOUR ALWAYS HUNGRY!!! (smell of your exhaust)
