It’s not really part of the narrative of the book but fatigue was only a contributing factor for ~13% of crashes historically so the maximum positive impact couldn’t be that large. Meanwhile there’s been a long term trend of significantly increased fatalities. https://www.fmcsa.dot.gov/safety/data-and-statistics/trends-table-7-large-truck-injury-crash-statistics-1999-2019 https://www.fmcsa.dot.gov/safety/data-and-statistics/trends-... The comments on studies looking back 1 year while the transition happened 5 years ago looks like cherry picking data to fit a narrative.

  Right, but the ELDs didn't create the metric. The metric existed long before that, it was just gamed to an extreme degree because there was no accountability. ELDs brought accountability and made it harder to game. They didn't create the metric, they just reduced the gaming.
