i don´t want to sound overly smart, but I am very certain one should design their car already with all those pitot tubes ,and airflowfield measuring devices and run all their windtunnel + CFD work with and without those devices -so two runs per change on the car.Of course you race the car without all those measuring arrays still...
I think all we see in Formula 1 is a little too much improvised and this all leads itself to false correlations and even ignoring effects which NEED to be represented in testing.
For example: wind speeds influence.
How many times did we hear drivers moaning about having been hit by wind influences..but i have yet to see someone who is constantly quantifying those effects -surprising when considering it has an effect even felt by the driver negotiating a corner...and equipment for this readily available off the shelf...
Don´t come up with weather stations rigged up at the pit straight ,we are talking local wind influence logging synchronised
with the rest of your data sampling .
