There're also similar roads 30 minutes from Silicon Valley that have all that, plus residences, pedestrians, parked cars, sheer cliffs, unclear driveway splits, and porta-potties, eg. https://goo.gl/maps/57jzzK6fvtCqvu5w5

Strangely I've never seen Waymo vehicles practicing on that. They're all over Mountain View, but I have never once seen them in the mid-peninsula hills.
