> driving is a mix of intuition and rules Intuition and rules and rule breaking. I remember back in Driver's Ed I was alarmed to discover that through sloppy definitions Colorado legislators had managed to make it illegal to take a right turn within 150ft of a stop sign (or similar, I forget the details). Of course, in reality nobody follows the sloppily defined portion of the rule, nobody enforces the sloppily defined rule, and it isn't a problem -- but the gap between rules and realities is substantial, self-driving cars are going to tease apart this gap, and spiders will come crawling out.
