Intuitively, Adam only got +2 mpg, while Beth got +10 mpg. So Beth is saving much more... 5 times more than Adam.
No, intuitively, Beth got 5 times more extra distance than Adam did for a gallon. I can see how it confuses people, and yeah less people would be confused if we used gpm because then people would see how much fuel they save per mile, rather than how much more distance they travel per gallon. If people are assuming that Beth saves 5x the fuel that Adam does, then they're just bad at understanding how maths works. I guess that's a lot of people, I guess that's something I take for granted.
