Get higher efficiency and most of our problem is solved.

Higher efficiency means MORE not less driving which will increase consumption there for driving demand

Not to worry; the statists have thought of that, and are planning on taxing us per mile.

"Higher efficiency means MORE not less driving which will increase consumption there for driving demand"

That is a false assumption. You are assuming that people will choose to drive more if their cars get better gas mileage. I don't think that will be the case. Most people drive the amount needed to go to work, etc., so they are not going to just choose to start driving more because their cars get better gas mileage.
