Trump hotels serve wealthy world travelers who arrive via airplane and limousine. Speaking of limousines, the completely self-driving car notion would be like riding in a limousine if it were possible. (It's not). No doubt the autonomous vehicle idea appeals most to those who ride in limousines and build exploitable markets of dependent consumers, in this case, everyone whose lives revolve around even the least amount of car-dependency, fuel/energy for travel and transport dependency. Trump hedges his stock market portfolio with munitions manufacture (Raytheon Tomahawk missiles) to by force acquire the petroleum resources his customers require to reach his spit cheap hotels.
