Those fins were introduced this year to prevent the cars from getting airborne when they go sideways; imagine what could have happened to Rockenfeller when he hit that Ferrari at 300+ kmh.. 
I agree on the visibility issues though! Try a few laps in rFactor or GTR2 in the Peugeot 908 around Le Mans; it's like looking through a letterbox..
