Regulation is regularly increasing the cost of a car by demanding more. For example, if you demand all new cars have a rear-backup-camera, then you added a cost.
Govt is intentionally trying to cause at least 2% inflation. If you assume only 2% average over 50 years. A $25,000 car then is only about $9000 today; an untenable proposition. Lets be realistic, do you genuinely think no government in 50 years will exceed 2%?
The $25k car is extinct.
