from J.G. Ballard's short story "Subliminal Man"... "All around him cars bulleted along, streaming toward the suburbs. Relaxed by the smooth motion of the car, Franklin edged outward into the next speed lane. As he accelerated from 40 to 50 mph a strident, ear-jarring noise drummed out from his tires, shaking the chassis of the car. Ostensibly as an aid to lane discipline, the surface of the road was covered with a mesh of smaller rubber studs, spaced progressively farther apart in each of the lanes so that the tire hum resonated exactly on 40, 50, 60 and 70 mph. Driving at an intermediate speed for more than a few seconds became physiologically painful, and soon resulted in damage to the car and tires."
