so the last 3 pages just confirm what i have been saying....
stop wasting time trying to eek out a minimal percent of energy impact from cars.... and increase that 10x by focusing current technology and best practices in buildings instead - there is NO substainal argument for "more efficent cars", its a waste of policy and production resources in the big picture. argueing about it just goes to show how duped and misplaced our awareness of energy is.
get a honda civic and call it a day - nearly zero pollution and fine economy, now focus on how we get to our buildings, and get your average building to near net zero and we can all have hummers and not worry about it
