This doesn't actually compare marginal costs. It factors in fixed costs like the cost of the charger for the EV amortized over five years. It counts road taxes for both types of vehicles, but road taxes are marginal for gas vehicles and fixed for electric ones. It doesn't count the additional marginal costs of maintaining an ICE vehicle over an EV. And all of the taxes come from Michigan, which is one of those states that charge EV and hybrid owners extra to register and have lower gas prices than the rest of the country. I'm almost certain this would give a different result closer to the coasts. This overall study feels like statistical cherry-picking to eeek out a marginal result.
