The problem with all that is that they have to comply with so much regulation. Every single part of the car is ruled by very precise rules that do limit the way a car can possibly look to a certain extent.
Personally, I do feel weird about that back wing, but I guess we'll just get used to it. As for the racing, I'm optimistic they wouldn't do this for no reason and it should be an improvement in the 2009 season. People say: "Ya, well, they'll brake later and there will not be as many passes". It's not entirely true. The racing should closer, so all the cars should be more bunched up together than they are right now. Passing will probably be indeed harder, but since they will be more bunched up as a whole, the number of passes will probably remain the same, although the result will be more fun to watch.
