What if eliminating the accident death externalities of pre-automobile transport systems, is only a fraction of the story of the externality equation? The shift to automobility certainly created massive positive externalities that we have taken for granted instead of crediting it to automobility. It is unfortunate that so many "popular" policy approaches to "reducing the negative externalities of automobility" end up foregoing positive externalities such as systemically affordable housing markets, the dispersion of urban pollution, the availability and reduced cost of land enabling productivity gains, and new clustering economies that could not exist otherwise.

And getting back to some pretty obvious gains that seem to have been forgotten; horses and draft animals were responsible for public health externalities in urban areas; and the land required to grow food for them was of considerable volume adjacent to cities, much more of it in fact, that urban sprawl has swallowed up since.

I would encourage you to read Noahopinion (Noah Smith) and his techno optimism/economics substack. Innovation happens in multiple dimensions, speeds and criticality continuously. I always think the irony is that we have the wealthiest, healthiest, most peaceful population in history but to achieve it we may have ended the world! On the "exciting" re maintenance and ops I look forward to hearing it. It is simply not true that politicians and the public are not excited by maintenance, just that it is expressed in the negative. When regular levels of service fail (trains, buses or roads) the public and media get very aggressive with the elected officials. Smart officials celebrate the level of service and justify the opex to avoid new capex. All the travel times savings palaver for new stuff and nobody seems to get that people move less speedily on poorly maintained services and infra! And with the amount of new infra coming into existence following this massive capital spend on the east coast if nobody is paying due attention to budgeting, efficiency and effort allocation a great deal of waste and unnecessary asset degradation will occur. See potholes after floods as a prime example.
