There’s a flipside too though. Straight lines aren’t great for suburbs for the speed reason, but once you reach enough density and the roads get narrow enough, grids make planning easier, and navigating easier for pedestrians. Roundabouts are a nice way to slow traffic through straight roads







There are residential neighborhoods in cities though, where straight roads with roundabouts and other traffic calming makes more sense than a curving a road, for the purposes of lowering driving speeds. Neither is better or worse inherently, we should just tailor solutions to the environment they’re needed in.
