Hypermilling techniques
The art of hypermilling, or using various techniques to get the highest miles per gallon from their fuel. Their cars display the miles per gallon being used right now, so that they can identify which driving techniques use the least and the most gas. Some say they can increase their mileage by 40%. One way is to run your car on water. Yes, this can be done by modifying your current car. Some hypermillers go to the extremes of drafting other cars, accelerating to the speed limit and coast as far as they can. Others use the old stand-by ways to save gas such as no jack-rabbit starts, driving the speed limit and making sure their tires are properly inflated.
