To carry out the fact that I have now raced with the same driver since January, I will cover up whether age makes a difference in performance.
And to be completely honest, my driver is now at 30 years old and has not got a cliff to show performance-wise just yet. It is still up to debate when she will get replaced because I have an academy driver fully trained up, but I will keep you posted as to how her performances change!
Here is the driver addressed in this post: https://igpmanager.com/app/d=driver&id=5356023
