Interesting perspective. Maybe i'm too influenced by the book "I'm A Legend" by Richard Matheson or the tv show "The Walking Dead". I remain surprised that the hypothesis of full autonomous activity would remain. In SF literature (beyond the example Rendezvous with Rama, from Arthur C. Clark) once civilization collapse there is no activity. So i would have expect the highways to be empty and effectively useless.
