The IRS estimates per-mile deduction at well over 60 cents per mile. If you have to drive 15 miles to the grocery store and back, your grocery bill goes up $18/trip. If you need to drive 15 miles to work and back, take $90/week out of your paycheck.
Then there's the fact that whoever is The Employer in that region - if you lose your job there, you're fucked. So The Employer gets to abuse every rule in th book because who's going to complain and risk losing their job? If The Employer decideds to drop everyone's pay by 25 cents/hour, what are you all going to do? Answer: nothing.
Meanwhile in the city you can go anywhere you want within a 500 square mile area (or more) for well under $100/month and commuter rail will take you even further for not a lot more. And you can do other things while using said transportation. No "self driving car" needed.
As a sidenote: the same author complains about the "loss of the $50 motel room" and laments they're 3x more expensive now. Days after complaining that housing isn't actually that expensive. The guy has to be a troll...
Oh, and also not factored in: almost every aspect of rural life is heavily subsidized, and I don't just mean direct assistance. I mean literally everything you stare at when you roll through a rural town was subsidized in some way by the federal government, and most of them either don't know or will never admit it.
For fucks sakes the government actually runs a program to subsidize rural Americans getting to fly around on barely-occupied turboprop planes. But heaven forbid a city get some federal funding for electric or hybrid transit busses that will serve several thousand people a day.
