On all the car audio-video forums they refer ICE as In Car Entertainment.
Your engine is generally most efficient at 70-80% throttle, but you then run into the aero problem again.
Ever try to run against 45 mile per hour winds during a storm? you don't get very far, and you get tired pretty quickly. A car at 70mph is having to push through all that air, which is also pushing you back. you go slow, you have an easier time. So most vehicles (autos specifically) have a sweet-spot between 45-55 range. Generally, that spot is around 45-52ish. Also, cars usually have a hard drop in FE for every 60mph, especially in trucks and SUV's. Mostly from the wall-like windshield.
I can go a lot farther on a tank going 50, but I rarely get to do that cause I'm usually carting around a lot of impatient people. they don't mind me doing 55.
