How to design a city?

Been reading this thread for a while, but got kinda bored by the really really really really really long, rebuttal posts that have been cropping up, not sure how much information is being spread by those who participate, and a lot of it is going over my head as the original posts that are being rebutted are damn long as well. Though the length of the posts (for clarity of argument I suppose) don't seem to be swaying anyone one or t'other, and just seem to add fuel to the discussion rather than clarifying anything.

I'll give that a big +1.

If you really want to have no cars / roads you can't have a city - you'll be needing a self-sufficient village where everyone works to provide the goods / food that the village needs. Not neccessarily a huge step forward for mankind through.
