The Great Plains, with all that flat, wide-open and sparsely populated land, has long had the most generous — or audacious — speed limits in the country. Cross the Minnesota border into South Dakota, and the default statewide speed limit on the interstates there, as of this spring, is now 80 miles an hour.
Idaho, Wyoming and Utah have also pushed their legal limits that far. Texas, meanwhile, has a toll road that tops out at 85. Which, as we all know, means there are drivers there traveling 90. The Missouri River, as it turns out, is a kind of speed-limit fault line: Most states west of it consider legal what Virginia, Ohio and Illinois would call “speeding.”
