Rural residents drive a bit more, but each mile they drive is nearly twice as deadly
I investigated what driving risk factors are in your control, driving slower or driving less, but I ended up looking at residence choice's impact on driving safety.
Counted by home county, rural residents drove 18% more miles per person in 2017 (NHTS) but died in traffic at 2.2x the rate of big-metro residents (CDC, age-adjusted). Per mile, that's ~1.9x.
Rural roads, speeds, and EMS response times all differ, so this is a correlation and not a claim that density alone causes the gap. The post also compares the safety value of driving slower vs. driving less. Code and sources are linked in post:
