Our brains are very good at understanding 1, 2, sometimes 3 and, “many”. That’s the data we get from smart chips, young children and isolated pre-literate societies.
Counting bigger numbers requires abstract systems. Our brains can do that but it’s much harder and we don’t grasp it as well.
The practical offshot of this is that while it’s intuitively obvious that a small space like a garage will quickly fill up with toxic gasses, it’s far less intuitive that a “very big” outside can get saturated by a “pretty big number” of cars.
