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.

THE TRUTH...

is the first thing despots go after. An unwavering commitment to it is probably what draws you to Mother Jones' journalism. And as we're seeing in the US and the world around, authoritarians seek to poison the discourse and the way we relate to each other because they can't stand people coming together around a shared sense of the truth—it's a huge threat to them.

Which is also a pretty great way to describe Mother Jones' mission: People coming together around the truth to hold power accountable.

And right now, we need to raise about $400,000 from our online readers over the next two months to hit our annual goal and make good on that mission. Read more about the information war we find ourselves in and how people-powered, independent reporting can and must rise to the challenge—and please support our team's truth-telling journalism with a donation if you can right now.
