I don't know what a good yardstick would be, but CPI is definitely not it. US CPI weights the entire Medical Products & Services category at 8.68% vs its actual weighting of 18.1% as a fraction of GDP. The average price of a new vehicle hasn't materially changed in 22 years in the CPI due to hedonic adjustments, whereas the actual sticker price is 55% higher.
