I've seen the results of this first-hand when a big rig about 10 car lengths ahead of me on I-5 abruptly began moving from the right lane through the center median and into the lanes of oncoming traffic.

He slammed into a pickup truck and killed that truck's occupant.

I had to be called in as a witness of the incident by the victim and trucking company's attorneys.

I think there's a strong difference between (rightfully so) blaming the companies that force this environment and the people who are just trying to make a living safely.
