Well, if you go West it is. The East is much like any European city - a warren of too-narrow roads. Which makes sense, as they were founded (by Europeans) when that sort of thing was common all over the world.
Here in Iowa, which became a State in 1846, we have a nominal 1-mile grid of secondary roads covering the entire state. To make easy access to land for agriculture. It was planned and executed by surveyors, business people and pragmatic colonists.
It's common in the mid-west. In much of the far west, it stops because lots of land has insufficient water and can be too rugged to be developed with roads at the road-every-mile level.
