It's likely pricing will be the new and effective justification per curbing our thirst. It's a bit premature.

Looks like future hotroding will involve veg oil and the diesel. I know some guys with pickups that can smoke most cars. They hit 70 to 80 getting on to the freeway and they're pulling RV trailers loaded with 100 gal. of water, 20 gal of gas and dirtbikes!
