After Generation

I would like to see a post generation rebuild. By rebuild I mean a way to fix such things as the straight lines and crazy looking cars wheels and othe rthings that don't look righ and seem difficult for the AI build. Basically, those things that seem strange get automatically fixed. Maybe better results could be had with a longer rendering period? Hope this makes sense. Maybe the creation of some details simply need more time to render. As an example of the craziness such things as cars and bicycle spokes that come out jumbled, or the details in a facade on a building. A post fix might realize the problem and fix it.
