It didn't take long to arrive at a plausible explanation: modern Americans are less willing and able than ever to restrain their passions. Come to think of it, "passion" is one of the few remaining things that Americans actually worship, as revealed in just about any television show or movie that Hollywood palms off as entertainment these days. Every character who displays self-control, sobriety, or consistent standards must endure merciless ridicule and punishment until he or she sheds those priggish qualities and joins the egoistic romp of modern American life. If the character refuses to change, then he or she is undoubtedly a villain. This cultural dynamic -- which is especially powerful in South Florida -- has an irresistible corrosive effect on all societal institutions, and the chaos on the roads is congruent to the chaos in the political system.
As the ancient Greeks properly understood, "passion" is a form of "passiveness," a surrender of the mind to one's blind impulses. One of America's Founding Fathers, Edmund Burke, accurately observed:
Society cannot exist unless a controlling power upon will and appetite be placed somewhere, and the less of it there is within, the more there must be without. It is ordained in the eternal constitution of things, that men of intemperate minds cannot be free. Their passions forge their fetters.
Americans now esteem "passion" far above reason or restraint, so it's no surprise that government is stepping in to fill the void. The vehicle that our ancestors gave us is running on fumes.
