Why Miles Per Gallon Suck

Our calculations about car efficiency tend to be wildly off the mark. The Fuqua (I am not making that up) School of Business at Duke University studied it every which way and found that improving the most energy inefficient cars with ones that are even slightly more efficient saves WAY more fuel than trading in your not-so-bad Honda Civic for a hybrid. Most of us assume otherwise. The problem arises from the fact that we’re talking miles per gallon when we should be talking gallons per mile. The video explains all.

We've never been very good at being conservative.

And usually, that serves us well in doing the ambitious, hard-hitting journalism that you turn to Mother Jones for. But it also means we can't afford to come up short when it comes to scratching together the funds it takes to keep our team firing on all cylinders, and the truth is, we finished our budgeting cycle on June 30 about $100,000 short of our online goal.

This is no time to come up short. It's time to fight like hell, as our namesake would tell us to do, for a democracy where minority rule cannot impose an extreme agenda, where facts matter, and where accountability has a chance at the polls and in the press. If you value our reporting and you can right now, please help us dig out of the $100,000 hole we're starting our new budgeting cycle in with an always-needed and always-appreciated donation today.
