Hopefully the noses of the other manufacturers will be closer to the 2012 McLaren this year than last years broken (stepped) noses.
It's pretty amazing how ugly race cars have become today. You think back to the FW14B or the MP4/7A, or 1990's era Penske or Reynard Indycars, etc. Then compare them to the stepped nose F1 monstrosities of today, or the COT in NASCAR. Maybe motorsport needs some kind of aesthetics rule? I understand the military going for function over form, but this is sport.
If they brought back proper ground effect cars, they'd be able to go for form and just hide the function without losing it.
