Humans also have prior world domain knowledge. A human driver seeing a guy running across the road behind an obstacle can infer that the human will probably pop out on the other side (and prepare accordingly). A human can see the silhouette of an object with 1 eye and still infer that it has depth because they know what objects are, which is why one-eyed people can drive legally everywhere in the US. This inference extends to everything, not just shapes but behaviors of anything in the road, animate and inanimate objects.
