Americans have gained weight over the last thirty years, and not just around the midsection. American garages and driveways have also put on pounds as cars have become larger and more powerful. A new study from MIT says that, if not for the increase in vehicle weight, we could already be exceeding vehicle mileage targets still years away.
Newsflash: Over the last few decades, cars have gotten both heavier and more powerful in addition to getting somewhat better fuel mileage. No shocker, right? Still, it's interesting to actually sit down and take a good look at the data to see what additional information can be gleaned.
