Well, okay, maybe that’s overstating it a little. But she did tell me on the phone a couple days ago that, having heard my spiel, she’s been experimenting lately with driving more slowly on the highway, which is where she does most of her driving. Previously she was going along with the high-speed flow, generally running at around 75 mph, and getting around 29 mpg. Now that she’s dropped into the slow lane, maintaining more like 65 mph, her efficiency has gone up to 35 mpg. A 20% increase in fuel efficiency! Way to go mom!
