Find the Center
The folks at DriveCam analyze driver behavior using video recorders installed on vehicles. (See highlights at drivecam.com.) Safety specialist Julie Stevens recommends sticking to the center lane on freeways. Rear-end crashes happen less there than in adjacent lanes. "Every time you change lanes you add risk," she says, "and the slow lane always has the most action." Other research has shown that the "chronic lane changer" saves a mere four minutes out of an 80-minute drive.
