The positive result of the Formula 1 Commission vote on wing changes intended to improve overtaking for 2019 came as a surprise. FIA president Jean Todt called the April 30 decision "a miracle".
That description reflects just how close the proposals came to not going through. Had one or two teams changed their minds and voted against, that would have been the end of it, and the current aero package would be in place for the next two seasons.
So who stands to gain from the changes? And will they really work?
