They probably could have also mentioned the power grids that were not designed to last as long as they have and certainly not designed to scale to everyone having EV's. That will have to be addressed sooner than later. Then there is the topic of methane gas distribution and water distribution. Some cities have aging pipes or worse have lead components in their drinking water pipes. This gets tricky because the budgeting for some of this is partially local and partially federal with a smattering of multi-agency bureaucracy. There is also an aging PSTN telco network that probably should have been replaced by a much more modern and high capacity network to support modern data protocols and rural internet connectivity.
