4-6 second range is an area where you will go during the following 4 to 6 seconds, and where you get the last update of how you are controlling your proposed way of travel.
Step-by-step explanation:
The 4-6 second range is the space you will go during the following 4-6 seconds. While driving straight ahead you will typically remain in a driving path except if different components influence the situation of your vehicle and change your way of movement. By this range the region you can see unmistakably and strongly is seen with your focal vision. The region you can see to one side and right of focal vision is your side vision or fringe vision.
