Fangio's judgments were not based on reflex. Incidents do not occur all at once. To move beyond the mere mechanics of operating a vehicle in a complex environment, a driver must foresee pitfalls. But, you can. Your own experience makes you an expert.
Racing drivers speak to one another by the lines they take.
Distinct movements and changes in a line telegraph intent, attentiveness, and competence. Recognizing divergence from the line is precisely what is primary to anticipate what should be and apply judgment to what should not be. Anticipation translates the laws of speed back to their original language, which is thought. A concept always precedes a driver's action. If the concept is flawed the execution will always be flawed.
