I feel like this article misses the big underlying problems of car dependency, and is mostly directed at dense urban centers which are already reasonably well equipped to ween off car use.
The real issue is reforming car first infrastructure and urban design. The science is clear: you literally cannot transit your way out of an auto-dependent suburb. People's homes are so spread out that having enough transit lines and stops to cover everyone would be astronomically expensive, and much slower than simply driving.
The solution to reforming the suburbs is twofold.
First is to give people reasonable options for living in less autodependent spaces by allowing and encouraging denser housing development in already walkable areas, and relaxing suburban zoning to allow walkable spaces to develop naturally in these areas.
Second is to, essentially, force people to stop using their cars via economic leverage. Gas taxes, carbon taxes, registration fees, additional infrastructure fees for sprawled suburban homes, no free parking, fees for using highways and fees for exiting highways into dense urban areas, etc. The reality is, cars are extraordinarily convenient, comfortable, and safe, and we will continue having ample roads for them to drive on for the forseeable future.
