Americans aren’t stupid. We’re just badly informed. And occasionally, stubborn.
Why else would we ignorantly cling to using miles per gallon as the way to measure how efficiently a car uses fuel?
But maybe you don’t quite see the problem. OK, so here’s a little test: Which saves more gasoline, going from 10 to 20 mpg, or going from 33 to 50 mpg?
If you’re like most Americans, you picked the second one. But, in fact, that’s exactly backwards. Over any given mileage, replacing a 10-mpg vehicle with one that gets 20 mpg saves five times the gasoline that replacing a 33-mpg vehicle with one that gets 50 does.
