Why can a small child crouching down to pick something up near the bus be especially dangerous?

Pick an answer

1. The bus's cameras always show a crouching child clearly, so the driver can see them from the seat at all times
2. A child at that height and distance can disappear completely from the driver's mirrors and windows
3. It's not a real risk since the bus isn't moving yet
4. It only matters if the child is wearing dark clothing
