As of last week, there are 289 additional miles of Utah freeways with an 80-mph speed limit. This is a relief, because the new limit nearly matches my wife's actual driving speed.More on that later.As for my driving, the 80-mph speed limit changes nothing. My family regularly mocks me for my habitual adherence to posted speed limits.Because I obey the law, I have been accused of driving like I'm "from Idaho." But I defend native Spud Staters against these false charges. As we all know, those who learned to drive in Idaho are not best known for driving slowly. If they are famous for anything, it's for leaving on their turn signals while motoring in the fast lane.
