Professional drivers, at least those driving Class 8 rigs, go slower to be more profitable. Their time is more valuable when they're better-disciplined drivers who do the math. Example:

60 mi/hr:
Daily billable miles: 600
Daily revenue: $750
Fuel consumption: 6 mi/gal
Daily fuel cost: $400
Gross daily profit: $350
Daily wear & tear on truck, tires, driver: 600 miles' worth

75 mi/hr:
Daily billable miles: 750
Daily revenue: $937.50
Fuel consumption: 5 mi/gal
Daily fuel cost: $600
Gross daily profit: $337.50
Daily wear & tear on truck, tires, driver: 750 miles' worth

It's just an incidental side benefit that they're safer, more relaxed at the end of the day, retain more of their hearing, buy fewer tires and their trucks last longer and depreciate less.

Consider the putz driving 85 on Rt 95 in Florida and trust me there are many of them. At 85 and even 90 the C/drag is tremendous, a 18 wheel with a 600 hp Cummins can do it but you are in the 4 mpg range.

And then there is/are the tires which are burning up at a much greater rate than linear because of heat build up.

The guy in his F-350 doing 85 isn't much better in my personal opinion.
