The front wings in 2009 were widened to decrease the loss of downforce from following another car due to the effects of turbulence, and imho, it was an effective measure.
In 2014, we are again seeing a lack of overtaking (despite DRS) in 2014 due to cars being unable to follow another closely. We saw much less overtaking in Sepang and Shanghai, tracks where we have historically seen some exciting races.
I think it was a mistake to narrow the front wings. I understand the rationale was to control the amount of available downforce, but the way they went about it wasn't the way to go. They could have kept the width of the wings but limited number of elements or number of end plate elements.
What do you think?
