Driving blinds you.
While driving we tend to blot out images on our periphery, in a phenomenon known as “motion-induced blindness.” It’s believed to grow out of the brain’s attempt to discard unimportant information, focusing, say, on the road in front rather than pedestrians on the sidewalk or passing storefronts. The longer we stare at an object in front of us, the more likely we will fail to see objects in our peripheral vision.
