It means, pretty much, that we are all out of ideas.
Concept cars seem to go one of two directions: bulbous, futuristic greenhouses dripping with luxury horseshit or these ultra V8 (Or more) powered rich-toys.
Yeah, there are trends, sure. But these trends aren't moving us in the proper direction. Once again I reiterate: The automotive industry began dying in 1989. It finally died in 1994 with the release of the 4th gen Supra. Cars in the 80s were so much more inspired, and had real substance to them. The Prius, it would seem, is the wave of the future.
Ever drive a Prius ? It's not like driving a car at all.
