I'd drive the Hummer but make some serious fuel saving modifications... like putting in a 350ci Chevrolet engine or something. They still have a long way to go in making energy efficient cars like the Prius an attractive option... they seem intent on always making them unsexy, as well as relatively powerless, to prove how earnest they are about being green. What they could (and might eventually) do, if traffic congestion is a problem in a city, is to let people hire them for within city zones to get around in and let no other vehicles in there. This would get people used to them, and alleviate the uncool stigma of using/owning them.
I saw a doco a few days ago on the Italian APE trucks and was pretty impressed though. They were originally based on a three-wheel Vespa frame. http://www.barganews.com/people/ape/
I have vague memories of seeing similar 3-wheeled milktruck vehicles as a child in Spain.
Ever cuckolded one of your 'friends' good and proper? If yes, you qualify for the question: How did it feel? Provide suitable details...
