Since I first posted this chart in the fall, Americans have been freaking about oil supplies peaking, telecommuting to avoid the pinch at the pump, and flocking to car-sharing services in city centers. Plus, our transmission gave out, forcing me to walk about an hour a day, minimum, and burn perhaps the greenest fuel of all: calories--no joke when you live on this hill. Car-less, I've been shopping a small bag at a time, shoving organic chocolate in my backpack and pedaling away.
For bulk groceries, it still seems that taking a taxi from the store is cheaper than sharing a car, plus it drops you off at your door for good so you don't have to march home from the lot. Now that a Zipcar office opened a block from work, however, I'm tempted to try it. Should I cave into the ever-expanding Zipcar empire, support the rival Flexcar, or support the local nonprofit City CarShare? See if the chart speaks for itself. What's your favorite?
