Of course cost per mile effects every driver. Total cost of driving includes all those things plus maintenance and mileage
That's a hard calculation/realization to grasp for the general public who has no real accounting need of those micro cost. You should try explaining to someone the cost of tires and brakes on a per mile bases and watch them glaze.
Knowing that kind of information can be helpful for everyone. When our first kid was born the only 4 door vehicle we had was my truck, so my wife started driving it as the baby hauler. Knowing the numbers and what I expected from gas prices, I figured out that buying her a 4 door Civic for $7k would pay for itself in about 3.5 years, then reduce our actual fleet cost, which it did. Of course the second kid banged-up those numbers a bit and magically made that Civic "too small" so it had to be replaced with a Pilot.
