55-mph was and is a crock. Oregon's rural interstates had a fatality rate of 0.8 -- FAR FAR LOWER than the 1.6-to-4.3 deaths per 100-million--travel-miles on other rural roads in 2015.  In fact interstates are the fastest, safest, and most fuel-efficient roads. No surprise: the common causes of crashes are opposing traffic, crossing traffic, roadside hazards, and sharp curves-- all minimized on freeways. The same crash-prone intersections are also fuel wasters. Since rural interstates only account for 7% of Oregon's vehicle-miles-traveled, how could monkeying with the limit change much?
