Your central and peripheral vision reduces whenever you ride a vehicle at a high speed.  The best way to compensate for the decrease in your field of vision is to turn your head so that you can look to your sides. 

When you ride a vehicle in a fast speed, then your peripheral vision will reduce that is why there is a need for you to follow the direction of the objects when you are travelling in order for you to compensate to the decrease in the field of vision.
