Cars are included in the CPI. Don't spread FUD. https://www.bls.gov/cpi/factsheets/new-vehicles.htm

The BLS has new car prices close to unchanged over the past 30 years." Whatever you think of the validity of "hedonic adjustments", this is certainly not what I would expect when BLS reports car prices as unchanged during that period.
To take a European example, a 1990s VW golf is smaller and slower than a 2020 polo.
