In many ways developing nations can and do have the option to skip auto-based transit and go directly into mass transit if only because many up and coming consumers don’t have the capital to invest into a depreciating asset.
India, Indonesia, much of LatAm, including Mexico, most of Africa, etc. They could make autos cost prohibitive (in many places they in essence are) and invest heavily in mass transit. Skip roadways and other infra for personal vehicles.
China is in the cusp. They could simply decide to ban cars nationwide after a vigorous campaign promoting transit values.
