&gt;&gt; but so much physical, legal, and regulatory infrastructure needs to change<p>Let&#x27;s go with that. Say that tomorrow Google finished the development of the car. It works very well.<p>Than it just need to find a single city that would agree to a wide scale deployment. And I imagine there are plenty of reasons why a city might want to do that. Heck if Google cared, they could legally bribe politicians. And it doesn&#x27;t even have to be a city in the west. It could be a city ruled by a dictator somewhere in africa. Or it could be a self driving car created by a chinese company, and china would be willing to take the risk to lead in this field.<p>So maybe the first city isn&#x27;t as hard as it seems.<p>Now what happens after a car has proven itself  in a city for a year or two ?Showing almost zero accidents, and all the other benefits of a self-driving car. How much will people everywhere would want it ? how much political support would it gather ? i imagine a lot.<p>Would such support and proof be enough for relatively rapid deployment of self-driving cars ?
