miowpurr writes "A new X-Prize for ultra fuel efficient cars has been announced. The winning car must 'carry four or more passengers and have climate control, an audio system and 10 cubic feet of cargo space. They also must have four or more wheels, hit 60 miles per hour in less than 12 seconds and have a minimum top speed of 100 miles per hour and a range of 200 miles. Those that qualify will race their vehicles in cross-country races in 2009 and 2010 that will combine speed, distance, urban driving and overall performance.'"

People driving through the night are much more likely to cause accidents because our circadian rhythms just want to sleep — blue light at around 450nm wavelength can fool them into thinking it's morning and keep them awake."
