>>28480586>picture shows light residentialThat's a suburb. Most of San Diego is a suburb, it's pretty low density.
>>28481687Residential areas were denser than suburbs today. It's essentially a few things that make any form of shared infrastructure not viable in most of the US:
- Urban sprawl has increased the distances between everything massively, and building infrastructure miles is expensive
- Zoning laws prohibit small businesses from opening up in residential areas, which could have helped reducing the distance to the nearest grocery shop
Technically, not even your residential suburban streets are viable, the low density makes municipal tax-dollar-income per mile of street too low to properly maintain them. In addition, you make your streets needlessly expensive by being like five or six cars wide - they're the same width as stretches of no-speed-limit German Autobahn.
