&gt;  Expecting humans to &quot;drive less idiotic&quot; is basically saying that google&#x27;s cars won&#x27;t work until human drivers are banned.<p>Or until there is a critical mass that people adapt their expectations of how many drivers violate minor road rules, like running a red light or running through a crosswalk.<p>Also, even if self-driving cars aren&#x27;t perfect, from the data we have so far, they&#x27;re still several orders of magnitudes better than regular cars. If every self-driven car today were replaced with a regular car, we would see more crashes, not fewer, overall.
