There's an upper limit on travel speed. A 75-mph Interstate, unless in a truly rural area (rare) will not allow a travel average that high. There is too much other traffic. It's hard to get above 70-mph, and it's useless for trip planning. Find the engine run time and do the calcs yourself. I have, in running a big truck, where FE is not the concern, per se. It's part of a larger calculation about profitability.

Tire life and the life of other truck/trailer components count in this. The "fastest" truck drivers are not usually the best paid. Just the opposite, in fact. For the casual observer it's hard to generalize as there are so many types of truck driving that relative speed doesn't say much.

But understand that the spread from low to high as to travel time is not so large as some might think. Traffic is traffic. And maintaining a very long distance from the vehicle ahead for braking trumps saving time. Four seconds is almost too close even at 60.

The poor and the stupid are your vibrantly diverse companions on this road. Texting, farting and their tiny minds wandering. Twelve year olds. Just able to hang onto the steering wheel, but not able to make mental calculations worthy of the name.

For someone who claims their time is worth more (gotta get there to pick up the TV remote!) ought to look wider about vehicle wear, and especially at increasing risks.

The envelope from 55-mph up may cut off at 62-mph or lower when major metros, etc, are figured for a long Interstate trip.

About the only thing I miss in a speed-governed truck is to see another pack of bumper riding morons overtaking me when I am also overtaking slower traffic. But now won't be able to pass at my cruise speed. Luckily I am paid such that this doesn't affect my income in main. I'm not likely to get another run before I run out of hours. And at the end of the year it wouldn't be that great an increase against higher truck expense and increased risk. The better companies have figured this closely. So it's quickly a non-concern.

Minimizing risk counts for more than being a dog with his snout stuck out the window. That's the image to retain for being drunk on speed. It's unlikely anyone will maintain an above 65-mph average on a trip of any length. Lane changing, accel and decel events mitigate against it for long term economy. Of which FE is only one piece.
