When it comes to infrastructure, the suburbs are subsidizing everyone else. As (if?) they transition, it will get a lot more expensive to reliably serve other areas. The wealthy rural denizens will be fine, and will likely transition to EV-dominated transportation. Large farming concerns will have no problem whatsoever getting fuel delivered.
And everyone else is screwed. The time to start adaptation is now. I’m reminded of when I was growing up. None of the kids I knew living on farms drove F-150s and Silverados as daily drivers. They all had fuel-efficient vehicles as runabouts. Like it or not, that’s going to have to come back. For a lot of rural people, the next car they buy is going to be the one they’re stuck driving when gas gets permanently expensive (and slightly harder to get).
