The idea of driving around with a glass of water on your dashboard may seem ludicrous, but if Toyota told you that a single glass of water could help you reduce your fuel consumption by 10 percent, would you think differently? Now, Toyota doesn't want you to literally place a glass of water on the dash. Instead, the company is pushing the idea that driving in such a way that a theoretical glass of water there remains full would reduce fuel consumption significantly. To spread the word about this fuel-saving concept, Toyota has created a website appropriately called "A Glass of Water."
