Car Gas Mileage May Not Be All It Seems : NPR
I’m not really sure how to react to this story from NPR: Car Gas Mileage May Not Be All It Seems : NPR Here’s a quiz. Which saves more gas: trading in a 16-mile-a-gallon gas guzzler for a slightly more efficient car that gets 20 mpg? Or going from a gas-sipping sedan of 34-mpg to a hybrid that gets 50 mpg?

But cars aren’t advertised that way in the U.S. I’m not sure I buy the setup of the argument (not having kids, I don’t live in a world where you wouldn’t just replace the worst efficient car) but that seems like a different argument. My problem is that it (and essentially the same story I found) doesn’t even bother to give a method to convert for yourself.
