No, they are not wasting their time. If the brakes are used a lot (as of course they are on a race track) then their temperature rises far above the ambient air temperature and a good flow of air helps to cool them. Quite often this is insufficient and the discs get hotter and eventually radiate heat visibly. On a normal road, especaially a motorway, the brakes will be at or very close to the ambient temperature and even lots and lots of airflow will not lower that temperature.
