This reminds me of when i was learning to drive. In the beginning I was only aware of what was immediately in front of the car, and as such, drove very slow and had pay extra attention because a lot of important stuff was coming in to my field of view all the time.
Now, when i drive i look further down the road, i plan out how to follow the road, i see the intersection coming up, and try to anticipate the routes of the other cars/bikes and that requires far less energy, than only processing the immediate surroundings.
