I entirely agree with your analysis, the "new car efficiency" pitch is outright propaganda from the industry, pretty much like in the PC world where running old machines is usually (unless running 24/7 at full power) much more energy-efficient (and cheaper) than buying a new one. Just wanted to point out "mpg" and other american-centric units left me confused and i had to look it up. Spelling it out would have helped me understand, coming from Europe where we used standard decimal units. For anecdote, the domain where Europe doesn't use a decimal system is time. A decimal calendar was introduced during the French revolution, but shortly removed from history (like many other progresses of that era): https://en.wikipedia.org/wiki/French_Republican_calendar https://en.wikipedia.org/wiki/French_Republican_calendar
