The problem is liability.
When I gave my first eco seminar, it was sponsored by Shell and Ford. (they paid for the food, the cars, the gas and the venue). Shell had their own fuel saving guidelines and I had mine, and I had to mish-mash the two into a coherent whole.
I was under strict orders not to promote stuff like EOC (not that I practice it, or easily could... as the cars used were dual-clutch automatics) or neutral coasting, as the safety nannies at those companies didn't want their names attached to a seminar preaching such heretical stuff.
Hell... we had a small row over tire pressures, too.
Of course, we know what best practice is. Those schools likely know what best practice is. But due to legal liability, they can't teach it to their students.
