Final answer:
Saccadic eye movements are rapid, simultaneous movements of both eyes in the same direction used to survey different parts of the visual field, crucial for tasks like safe driving.
Step-by-step explanation:
The term for continually shifting eyes from one area of the roadway to another is referred to as saccadic eye movements. Saccades are quick, simultaneous movements of both eyes in the same direction to rapidly inspect varying parts of the visual field or to track moving objects. For instance, while driving, a person may make saccades to efficiently survey the surroundings, which could include the rearview mirror, the speedometer, and the roadway ahead, to gather vital information and react to any changes in the environment. This ability can be crucial for safe driving, as it helps in anticipating potential hazards and maintaining situational awareness.
