The author's premise does not hinge of the price of single items. Sure, a Dodge Caravan in 2018 may have a lower inflation-adjusted price than the 1996 model, but the author never claimed that every individual item's price increased faster than the measured rate of inflation. He looked more broadly at the amount the median worker spends on transportation. No one buys just a Dodge Caravan. They buy the Caravan, they pay for it with a loan of a significantly longer time than you'd get in 1996, they pay for more gas (longer commutes) that is more expensive, they pay for car insurance, and tolls. This total transportation cost (plus other mandatory necessities like health insurance and rent) have grown faster than the median worker's wages.
