The logic behind that is simple. Most of the nation's driving happens on slowass roads. Highways are safer for several reasons, despite being significantly faster. First, they're wider. Second, there is no oncoming traffic. Third, natural vehicle spacing is larger. Fourth, there's more lanes to manuever into to get around a bad situation. On your average one-lane-each-way road, you have basically one option for avoiding an accident - BRAKES. Go into the other lane, head on. Go right, guard rail, embankment, parked car, telephone pole.
But there is no logic behind doing twice what conditions permit and then causing all hell to break loose for an entire region (see: Baltimore City, Baltimore County, Harford County this past Friday)
