And each and every one of those elements was designed to work best in clean air. That is why most races are won in Q3 or the first turn. The car that leads after the first turn can regularly gain an advantage of more than 1 second before DRS can be activated. Then it's a cruise to the finish. Only some anomaly like rain, a crash or a safety car can upset the inevitable. Th entire approach to aero needs to be overhauled. Because F1 cars are way too dependent on aerodynamics to enhance grip.
