It's no coincidence the world's largest automaker chose California to showcase a fleet of futuristic low pollution vehicles it says will one day change the planet. Nor that eight foreign and domestic automakers and four of the world's largest oil companies are teamed just across the Sacramento River from the state Capitol in an unusually cooperative venture to develop and test hydrogen-powered fuel cell vehicles, according to the Associated Press. The Bush administration has joined the automakers in a court fight against California standards they fear will spread to other states -- prompting harsh criticism from Democratic Gov. Gray Davis -- even as the Republican president promises $1.2 billion for research and development of the hydrogen-based technology, AP reported. President Bush said the generation born now could be driving the cars that will wean the world from the internal-combustion engine to a pollution-free dependence on the universe's most common element, according to AP.
