Apologies for arguing the analogy, but the Benjamin Button car buyer would lose horsepower and weight (=safety and convenience features) to continue to make man

Apologies for arguing the analogy, but the Benjamin Button car buyer would lose horsepower and weight (=safety and convenience features) to continue to make mandated fuel economy standards. You could buy a 50 mpg CRX HF from Honda over 30 years ago, but you'd probably be very unhappy with its performance today. Small relative increases in fuel economy don't save you that much money, either
