Love it or hate it, using cruise control on the highway will make you drive more consistently. When your car’s engine maintains a consistent RPM, it reduces your fuel consumption (well, unless you’re taking a rare uphill trip…). According to Edmunds.com, using cruise control on the highway will increase your gas mileage by 7 percent. Not bad!
Cruise control also prevents a driver from reacting to every change in traffic—all of that acceleration and deceleration adds up. Reduced fuel equals reduced emissions—and added savings.
Cruise control can take some getting used to. Just because you’re cruising doesn’t mean you can stop paying attention to the road! Sounds silly, but this is an important reminder.
Play around with it until you’re comfortable. Optimal settings for cruise control include highways, interstates, and straight country roads.
