Dr. Alvah R. Lauer, associate professor of psychology at Iowa State University in Ames, Iowa, is attempting to find out why some auto drivers get "all tangled up" in traffic while others get through safely and easily, with a new auto drivers' test he is now developing. The driver taking the test, seats himself in an auto body in the college laboratory, which is equipped with the standard controls of the ordinary car, and looks at a miniature landscape which revolves toward the driver on two rollers. On the road in the landscape is a toy car which is guided by a mechanism connected to the steering apparatus of the car in which the driver is seated.
