They are looking without seeing

By Ronald A. Rensink:

A large fraction of traffic accidents are of the type "driver looked but failed to see". Here, drivers collide with pedestrians in plain view, with cars directly in front of them, and even run into trains. That's right - run into trains, not the other way around. In such cases, information from the world is entering the driver's eyes. But at some point along the way this information is lost, causing the driver to lose connection with the reality. They are looking but they are not seeing.
