Well, yes, obviously.

But your correspondent's analysis has other flaws, too. His 'average speed' calculation is an interesting one, but because he is working on the total cost of the car (as opposed to the incremental cost per mile) it is only really a valid figure for comparison for someone who is thinking about not owning a car at all. That works for some lifestyles in some places, but not for most.

Plus, he has completely failed to account for the value accrued from the enjoyment of driving fast. Silly man.
