My favourite example of SA is based on drivng the car. This is maybe something everyone can relate to?
Imagine you are driving along in your car during rush hour traffic in a built-up urban environment. The road has two lanes in each direction with numerous roads to the left and right.
You are in the left lane. The person in front suddenly indicates and brakes to turn left.
If you have no SA, you will run into them.
If you have any SA at all, you will brake behind them.
If you have good SA you will already be aware that they are going to turn left. Their road positioning, loss of speed, etc will have clued you in.
If you have excellent SA, then you will already be aware that they are turning left and wil have a strategy for changing lanes, including being aware of where cars in the right lane are located.
Any comments?
