A quick blip on riding in the normal traffic lane

The always interesting XKCD comic did an graphic on a person's visual field.  It immediately reminded me of a fundamental reason why safe cycling experts strongly suggest riding in the primary focus points of a driver ... the center of the lane.

Experiment with the graphic below to see how much less detail and color we see outside a narrow band of the focus point.  Riding to the far right often puts the cyclist in a location where they are less likely to be cognitively recognized and actively accounted for by the driver.
