The data is not broken down by road type.

Injecting the anti stroad agenda helps nothing. Its not relevant here. It mutes whatever truths the anti stroad people have and thier advocates get categorized into annoying wackjob category.

The cause was easy enough to identify: Data parsed by Kuhls and her colleagues showed that drivers were speeding more, on highways and on surface streets, and plowing through intersections with an alarming frequency. Conversely, seatbelt use was down, resulting in thousands of injuries to unrestrained drivers and passengers. After a decade of steady decline, intoxicated-driving arrests had rebounded to near historic highs.

“Drivers were frustrated,” says Kuhls, now a professor of surgery at the Kirk Kerkorian School of Medicine at U.N.L.V. and chief of trauma at an affiliated public hospital. “My own theory is that whatever personal conflicts they had were exacerbated because they’d been sheltering in place during Covid. So they’d get on the road having self-medicated with drugs or alcohol, or they’d just be incredibly reckless.”
