Our brains are pretty good at image processing. Plus we have an inherent understanding the world, including the way objects rotate and change shape. We're looking for the stop sign (big red hexegon).
Though I've seen a new stop sign added recently, and the number of cars that don't see it is remarkable.
I'm not an expert on AI though ( a few classed at university and I specialized in something else).
Its the general classifiers that give us trouble. We want to show it 100s of stop sign pictures and have it figure out when we show it new one. But we're not asking it, is this a stop sign, we're asking "what is this".
We can write software that probably is good at finding hexagons and colors and thus stop signs. Take facial recognition, its remarkably good at this point, but its doing one thing ( though I've seen a computer id 3 people in a photo with 2 in it , because a third person's photo was in the background.)

These two sentences together show that our brains aren't just looking for the signs; we're also looking at many other aspects of the situation and even taking into account past experience (e.g. is this an intersection? Have I seen a stop sign here before? If I'm new to this area, I'm likely going to be far more alert to the signage.)
If someone planted a (non-modified) stop sign on the side of a highway, where the road is completely straight and with no intersection, I bet some drivers won't even see it, those who do will be puzzled, and approximately none of them will even try to stop.
