What a great idea. Give the cities to the disembodied sovereign cars, and we&#x27;ll all just hide from them in our cubby holes, and pray that maybe once in a while we&#x27;ll be able to catch a ride as hitchhikers.<p>I can see it now, roadways filled with traffic jams, and nobody sitting in any of the cars, and no one having any idea where the cars are going, or why they&#x27;re even doing anything at all. Millions of puttering machines answering to no one, punctuated by the occasional pedestrian fatality, as would be demanded by statistics and the law of probability. But technology marches forward as a higher GDP beckons.<p>Sounds like a great idea. Let&#x27;s surround ourselves with haunted machines that blend in with the rest of the herd amidst the rat race, and add meaningless noise to the ambient signal of our bustling environment, so nobody will know whether nothing is actually happening or not.
