13. Use Cruise Control on Highways to Save Fuel and Reduce Fatigue
Constantly adjusting your speed wastes fuel and tires you out. Engage cruise control once you reach a steady highway speed (ideally 55–65 mph). The car maintains constant speed without your foot on the accelerator, improving fuel economy by up to 10–14% compared to manual control.
Modern adaptive cruise control even adjusts for traffic ahead. Real drivers use it on long trips to stay relaxed and consistent, avoiding speed tickets and unnecessary braking. Just remember to disengage it in rain, heavy traffic, or winding roads for safety.
