A good awareness test to try (on a barren road out of the city and away from any traffic) is to slam on your brakes at various speeds, and in various conditions (dry/wet/pouring), and observe how much time it takes for you to come to a stop. Bonus points if you're still in your own lane when you arrived to that complete stop.

The former means that you'll be travelling a longer distance before being able to react to something like seeing a pedestrian entering the street. The latter narrows your peripheral vision such that looking straight, you won't be able to detect movements on the footpath and crossing streets.
