This week at TreeHugger: UPS has unveiled what the they're calling the world's most efficient delivery vehicle—though don't be disappointed if the one that rolls up at your door doesn't have flames on it. While disgruntled motorists go the exta mile trying to get gouged as lightly as possible, a prize-winning journalist traces a gallon of gas along its twisted journey from a Chicago filing station back to its source. And for the hybrid drivers in the house, if you're pumping up the AC to cool off, you may end up pumping a lot more gas, too. The State of NY is revving up to convert 600 state vehicles into plug-ins, and the ever-greener Chicago gets ready to host the Eco-Transportation Show. And in case you worried about your kids learning proper American values, Happy Meals now come with a free Hummer. WTF?
