Here's a question: Does the study examine differences in the range of speeds used on the same roads at the same time? I would imagine that if everyone were going 80 mph they would be driving much more safely than if people on a highway were driving a range of speeds from 50-80. I'm sure that if everyone were driving 80 they'd have a higher risk during the time they were driving than if everyone were driving 50, but they would also be on the road at least 40% less time than those driving 50, so their overall cumulative risk may be lower even though their minute by minute risk may be higher, as you calculated.
