Try to explain that large vehicles don't perform, they simply run. There should be no use of "passing gear". Large road engines like nothing more than stability. Once on the highway, every time you move the accelerator you're wasting fuel. You get on the highway, set the cruise at your moderate speed, and let it run. If you come upon a slower vehicle, you're paying attention so that in a timely fashion you simply move left and drive around him. You don't accelerate, you don't downshift, you just cruise around him. If you're running a diesel, you likely have a sophisticated transmission as well. Set the cruise and steer. That's your job. Let the Cat and Mr Allison handle the RPM and the shifting on hills. They have enough electronically controlled efficiency profiles and safety protocols such that no human can possibly run the power train more efficiently or economically.
You don't "drive" large vehicles in cruising mode, be they buses, boats, or aircraft. You guide them by managing the systems. This is how professionals operate, and this is how all large vehicles should operate.
If son won't follow the protocol, then he's not skilled enough or mature enough to be trusted with your lives, and he can see the country from a side window.
