Once, in the middle of the day when it was bright and shiny, I pulled into a lot. I realized it wasn’t attached to the place I wanted to go, so decided to go through the lot and head out another entrance. Except the two lots weren’t connected. In fact the lot I was in was raised about a foot higher than the other lot. My tires stopped right on the very edge. Again, this was in the middle of the day with the sun shining. And it was obvious as fuck, as well.

You think you would notice, but the fact is your brain pulls crap like this on you all the time. Right now you can’t see the holes in your vision caused by your optic nerves. And it isn’t that your visual cortex is merely taking data from one eye to cover a deficiency in another. Close one eye and the hole is still not visible. The visual cortex and the systems it is connected to let you see what they want you to see. I am not asking how could he not notice, but rather, what was his brain doing to make him not realize. Because even in pitch black, with headlights it would still be visible that there is no bridge.
