Gas prices are climbing again, and some drivers are looking for savings in all the familiar places. But the answer may be sitting on the roof of the car, not buried under an old blanket and three emergency water bottles in the trunk.
AAA reported on September 17 that the national average for regular gasoline reached $4.43 per gallon. That price sits more than $1 above the year-earlier average. That makes a permanent roof rack worth another look. A rack, cargo box, or bike carrier can add aerodynamic drag every mile you drive, especially at highway speeds. The extra fuel use may not show up as a separate charge on your gas receipt, but the car still pays for it.
