I have done the road trip from Michigan to WDW many times over the years and can remember thinking more than once, "Are there any police in this state?" I would drive for hours without seeing a trooper or a deputy or anybody. Just about every car was driving 90-whatever mph, other than through the urbanized areas like Cincy/Knoxville/etc where traffic got serious. It sounds like public opinion has finally forced the government's hand in some of these regions.
