Thanks in part to Charles Darwin's theory of evolution, mankind believes everything's gradually getting better. It's a pretty strange kind of optimism, what with killer uptopians like Adolph Hitler and Joseph Stalin hanging-out in our collective past. But this faith in the eternal sunshine of the spotless future fits in nicely with the whole New Year's thing. As does The Detroit News (DTN) January 1 feature "The Road Ahead." Given the black cloud of bankruptcy hanging over Detroit, writer Bill Vlassic's desire to spread a little holiday cheer with a bit of automotive boosterism is entirely understandable. But there's a big difference between lightening-up and enlightenment.
