This comment from Reddit pretty much sums it up:
- The stats for the study came after 2 of the worst snow winters in decades.
- They counted crashes not directly on the highways, but on neighboring streets off the highway as well.
- They used gasoline sales in the area as the measure of traffic (despite there being automated count and speed stations).

Average speeds actually went down after the change due to abnormal winters. Raising the speed limits in 2014 came with zero real-world effect - because that's the speed most everyone was driving since 2004!!! How can they claim that raising the speed limits raised the collision numbers when the real-world travel speeds stayed the same or went down?
