人们甚至可以稍稍改变自己的生活方式，通过给轮胎适当加压，在高速公路上开慢一点（90公里/小时是最省油的速度）以及停开自己的SUV这些方法来节省能源。
People could make even simpler changes to their lifestyles by properly inflating their tires, driving more slowly on the highway – a car is most fuel efficient at about 55 miles (90 kilometers) per hour – and abandoning their SUVs.
