As part of a large research organization, I was involved in multiple studies about increased traffic fatalities. This work began in 2020, and was part of a larger epidemiological effort. Our findings contradict the headline, but are in agreement with the body of text. The most significant causal factor we found was the rise of mobile device ownership and usage. In fact, mobile device usage is the reason for the inflection of year over year decrease in traffic fatalities in 2012.

The article states that 10% of the fatality increase can be attributed to vehicle size. This is far below the actual increase, and while a contributing factor, not the primary one.
