Spending less on gas does not require treating every trip like an economy-driving competition. A few changes to speed, acceleration, idling, tires, cargo, and route choices can reduce fuel use without making every commute painfully slow.
The U.S. Department of Energy notes that aggressive acceleration, hard braking, and speeding can substantially reduce fuel economy. It also points to vehicle maintenance, unnecessary idling, excess weight, and aerodynamic drag as areas where drivers can waste fuel.
