Debatable is an understatement. their discount model is completely disproportionate to the benefits that those features bring. If an auto now costs 50% more, and CPI really is 0% increase, then I expect to see a monetary benefit of 50%, either through reduced maintenance cost, increased MPG, or maybe it makes me breakfast of the equivalent cost. but, I don't see new cars have anywhere near this benefit.

And it becomes even more preposterous when you look 50+ years back. CPI, says x3 increase in cost of car, but it's actually about x10. So, how does a car return +233% of it's value to a user when MPG hasn't even doubled over that time.

i mean sure, monetary rewards are not the only advancements but they should the primary basis for the inflation discount model. those auto-dimming mirrors and countless other features just don't mean very much.
