In this long-delayed episode, we explore all the business decisions behind the large, miles-per-gallon numbers you see on a window sticker when you go car shopping. We discuss what regulations govern fuel economy for cars sold in the United States, how the numbers used for regulatory purposes differ from what you see on the window sticker, and how fuel economy regulations can influence the cars that automakers sell in the United States. 

We also make an exciting announcement about rental car roulette and catch up on some administrative things.
