I think you’re doing situational awareness a disservice, and I’m guessing you’ve never worked in a field where it is a trained discipline.
It is not just paying attention to your surroundings, it is actively scanning and evaluating to anticipate changes to your situation.

It is more applicable to the physical world than any software domain.
