"One million simulated miles are not worth a hundred real miles in terms of confidence in the system" I'm wondering why you say that? Wouldn't the more relevant factor be the type of miles, regardless of whether they are simulated or real? For example, 1 mile of simulated "Interesting Scenarios" (Duck on Street, Bicyclist going wrong way, pedestrian running onto road) is likely worth 100,000 miles of normal Freeway driving.
