Most of the charges you list are mostly fixed (with time) rather than variable (with distance driven). Yearly service and yearly tire swapping: doesn't change by miles. Batteries and wipers: mostly fixed. Depreciation: probably 80% fixed. Insurance: mostly fixed. Registration: totally fixed.

On a marginal basis ("what does it cost me to drive one extra mile?"), I think my cost is about 7-9 US cents on my electric and about 12-15 US cents on my wife's CR-V. On an overall basis ("what does it cost me in total for the cars divided by how many miles I drove?"), the figures are more like $1/mile for the electric (still have a car payment, full insurance, and only drive 4500 miles/year) and $0.30-$0.40/mile for the Honda (paid off, so just carrying insurance, registration, taxes, and some timed maintenance items)

If we moved farther away, our fixed costs stay about the same, and it's only the variable costs that go up.
