Why is it that there are never any new developments featuring a grid street pattern like most older developments? Is it for traffic safety, road commission regulations, public demands, etc? Why do most residential developments feature a road layout that makes it difficult to get from one side of it to another? I've heard people describe it by saying its designed like throwing spaghetti on the wall. In my town and many others there is a traditional street layout with a few arterial roads spreading out from town and every new development is not aligned to it and does not allow for a smooth and navigable route throughout the town. Some developments even feature stub roads that just end at the backyard of another home! I'm interested in an answer from individuals who may have a better understanding of the politics and details of current design than I do.
