Cruise control and fuel economy

This is a tricky #FuelFact because the answer is a yes AND no. If you're on a long, flat motorway, then the smoothness of being on cruise control means your car will drive more efficiently because you're saving on unnecessary acceleration and braking. However, using cruise control during regular road conditions will end up using more fuel than required because cruise control can't foresee that hill ahead, meaning it'll take up extra fuel to make that change. Look at your road conditions and decide if cruise control is the way to go.
