It's been that way (as a test) for a long time now. Usually I drive it in my truck and drive 81. When it drops to 75, I drop to 79. It's a gas mileage thing for me. And my Porsche is at 3500rpm or so so I don't need to go higher than that unless a cobra passes me and I feel the need to Xibit. It is nice though to feel free about the speed you drive. Nice.
