How are steep and hilly roads of San Francisco similar in style to flat, grid-like roads of Phoenix?

[robertlagrant]

Well, for example if you drive in Europe you'll see much narrower roads, way more pedestrians and crossings; all sorts of things.

Right, so what you really mean is urban vs highway driving. In self driving, urban driving is considered much more challenging precisely because of the characteristics you listed. That's why you see Waymo only now dipping into highway driving because the primary taxi market is all inside busy cities.

No, I don't mean that.

Then I’m afraid you’re unclear because the cities Waymo operates in all have different characteristics and don’t have “similar style of roads”. Driving in SF is very different from driving in Phoenix.
