How to get rid of dirty air

If dirty air makes passing difficult, how do you eliminate it for better passing?

The reason I mentioned dirty air is that there is a very correlation between the starting grid and the actual race results. I haven't done the analysis, but my hunch is that in dry races 8 out of the top 10 on the starting grid will finish in the top ten--why spend 2 hours watching the race when the result is largely pre-ordained? Almost makes numbers 11-20 superfluous. If you could get rid of dirty air, the cars could get closer making passing easier to achieve.

My point was that if the driver can't overcome the dirty air, the race result has largely been determined on Saturday. Maybe Sauber has a weak car with solid drivers...the drivers can't overcome both the weak car and the dirty air...
