And why do they use them in the suburbs? And why do people express disdain for interconnected roads? Because nobody wants hundreds of cars going 40mph+ buzzing past their house every day. And instead of taking the time/money to fix the root cause, people who can afford to do so build culdesac neighborhoods. Edit - and to be clear, I don't blame any individuals for making that choice. We're kind of stuck with what we have for now - any change/progress will be slow and incremental. None of which means we shouldn't design better/safer neighborhoods/roads.
