I know I am. In the future, since it's unlikely I can afford a hybrid car, I would like to get a diesel auto and convert it to run on waste vegetable oil/biodiesel. Prefer VW van, 4wd. I also used a lot more heating oil this winter since i ran out of firewood. And, my community needs a lot more bike/foot paths, I would fear for my life riding down the road i live on.
