The brain allows the driver to anticipate and, therefore, is his best ally. Ground rush is caused by failing to continually adjust vision further ahead, particularly as speed increases. Escalating speed magnifies anxiety. As visual depths of field get shorter with increasing speed, anxiety progressively grows. If this cascade of events continues, once eye placement is inside reaction distance and speed continues to mount, eye movement becomes fixed and scanning for crucial information stops.
Fear is the result of progressively increasing anxiety.
Fear brings panic inputs, and involuntary panic input is always wrong. The quickest indication of an unskilled driver is the hurried move. The hurried move does not come from starting a skill to soon but from neglecting to finish the skill that preceded it, cutting it off short. Skill is simply performing in a higher gear where there is less of the grinding inefficiency of a lower gear to multiply task difficulty. Skill allows you not to rush and lets you have time to choose when to rush.
