Although it demonstrably reduces pollution levels, I don't see it go much further. Too many of us are obviously willing to pay any price for the ability to sit in our own tin can while producing smog and traffic jams. Even when not in use, cars are a massive waste of space that clogs our cities. Until we find something that's at the same time ridiculously much cheaper, less wasteful and less toxic, we will stay stuck, clogged, jammed and suffocating.
