I just want to point out that those car CO2 figures don't go to very high fuel efficiency rates. I have a prius c (high on the efficiency scale, I know) and I just calculated about 290 grams of CO2 per mile (about 50mpg). Still not amazing, but a good bit better than 390g CO2/mile. That's just for one passenger as well.
