Our planet may be in trouble: according to Top Gear, the best-selling car in the world is the Ford F-150 pickup truck. They are sold at an astonishing rate of 107 every hour of every day of the year, which means two or three went while I was composing this paragraph. Getting only 14/20 mpg, that's not good news for anyone except Exxon and several dozen lucky Sheiks.
What's even more astonishing is the bulk of these sales are in North America alone. Thank goodness for that--if the Chinese started driving and buying these behemoths at the rate Americans do, well, it would be like a global-environmental version of when everyone flushes their toilets at the same time and the water mains all explode.
