I'm new to forums like this as my previous 15 years of employment prevented me talking much about what I did. However, for the past two years I've been part of the aerodynamic team working within F1 on the 2021 rule set. Today these rules, following consultation with the teams and then unanimous approval by the WMSC, have been released to the wider public and where possible I'd be happy to try and answer any questions you might have about them.
There will always be differences of opinions, especially around something as subjective as aerodynamics but whilst you might not agree with some of what we have done or tried to achieve I won't continue to participate in the face of outright negativity.
In the meantime, ask away...
