Yank stupidity always continues to amaze me, it is one of the constants in this world, along with whinging pom backpackers ('It's so hot!').
This article really amazes me. In order to reduce dependance on foreign oil imports they could encourage car makers to make use of more environmentally friendly energy alternatives like the Toyota Prius and Peugeot 307 HDI, instead they decide to allow oil drilling in a massive nature reserve.
I found something interesting on the Toyota US site, it shows all the Toyota models sorted by fuel mileage. Prius leads the pack at 51 mpg, and the Landcruiser brings up the rear at 17 mpg. http://www.toyota.com/vehicles/modelselector/mpg.html
