Why athletes need a ‘quiet eye’
When I was taking driver's ed as a teenager the instructor showed us a video that illustrated a driver's gaze from the first person as they drove using a small circle. The difference between a skilled, competent driver and a student was that the competent driver only fixated on things that were likely to matter. So mostly their gaze was on the vehicle in front of them, followed by any place that could hold moving objects and pedestrians, then briefly signage. In contrast, novice drivers' gaze was all over the road, the signage, pedestrians moving parallel to the road--in short they had no mental filter for their attention.
