Do you really think a middle aged truck driver is (was) holding the steering wheel for 16hr straight as a matter of routine business? Of course not.
Tropes like that make for easy online virtue points but that wasn't the reality for the overwhelming majority of people who were cooking the books.
These guys were putting in 60-80hr 6/7 day weeks. It's no different than the plant maintenance tech or the IT guy doing the same thing. What they sacrificed was their outside of work life. Nobody is working those kinds of hours and having a life outside work. You would have physical complications from that in very short order.
And occasionally someone would go overboard, drive 36hr straight and cause a crash. And because that's an easy thing for people who have zero knowledge of industry incentives and feedback loops to get their panties in a knot over they made it "extra illegal" because you can't make being an idiot illegal.
And so now the industry cuts far less tasteful corners and pays everyone crap and you have drivers who have barely memorized the pre-trip, have barely and hours behind the wheel, can't read english, and who choose a different career in short order and are likewise treated as disposable.
So the net effect is more or less a wash but a handful of people get to get big raises and some politicians can pat themselves on the back for "solving" logbook fraud.
