Can you tell the fellow who did this off Highway 24 to take a brief nap why this is such a bad idea? > A: I sure can. It’s the “moth effect.” Traffic cops say drivers sometimes inadvertently steer toward a disabled vehicle or a pedestrian on the shoulder, like a moth to a flame. Their advice is that if you must stop your car, pull off the freeway and remain in your car with your seat belt fastened and emergency lights flashing.
