formula is limit = 85% of drivers travel at or under the lmiit
That means that the prior limit of 55 or 65 (as they are upping the limit to 70 mph, had more than 15% of drivers on the road driving above the speed limit? well, duh!
So they up and that means there will still be 15% driving above the limit? Hell, up it farther then and you won't have as many speeders....
wait, that would eliminate a whole chunk of public revenue...
jeez
