Idea to ponder... variable speed limits

So it kids are around, they already have signs that tell you that you must slow to some stupid crawl speed... and if you are doomed to travel through a reputed construction zone (and we all know you'll never see any construction going on at least 1/2 the time)

So since they already have variable speed limits when it works against us, I propose that we vote in variable speed limits that make sense and that we will enjoy...

90 mph on interstates at night, there isn't any traffic, there aren't any kids wandering onto them.
highways should go from 55 to 80 at night
city streets from 35 to 55 at night
