That's the point of this comment chain. They don't have to make it work everywhere in the contiguous United States to have a useful product. The (robo)taxi market is concentrated in big metro areas and that's what their focus is.
The thing is, with apps providing start and end point, they don't even need to be able to handle a full city to get a benefit. They can geofence really aggressively, and the moment they can ditch the safety drivers from a sufficient subset of journeys based on routes requested, they have an advantage.
Exactly. They can outright ignore really hard markets,. and be present in markets that have a decent percentage of routes they can handle and fall back to dispatching regular cars on routes their full automation can't handle.
