How about a little bit more creativity when engineering your next supercar?

Looking at the recent announcements of new supercars arriving (i.e. Ferrari 458, McLaren MP4 12C, etc.) I wonder whether their designers and engineers do not lack a bit of creativity. Of course they add power and improve handling and overall performance with each new car, but compared to what is happening in the compact and economy car segment, these are baby steps. Look at the Nissan Land Glider for example, isn't this impressive? I would really appreciate if Porsche, Ferrari, Maserati or Aston Martin would come up with a truly creative approach on how to combine performance, handling, usability and economy in a next generation supercar.
