I ride Waymos in San Francisco that traverse longer twisting "two-way" roads in the San Francisco hills (look at the neighborhoods around Mount Davidson). In these cases, the road, while two way, more often than not only has space which allows a single car to pass at a time; the rest of the space is taken by cars parked on either side of the roadway. The Waymo cars. at least during my rides, handled these situations well.

While it's not Rome, the operating areas for Waymo, at least in San Francisco, are not all grids of modern wide streets either.
