I would bet more in a company who figured out the last 20% in a specific city than a company stuck on the first 80% generally.

Waymo does not have cherry picked routes - it has a defined ODD inside which is ANY route can be driven fully unsupervised.

This necessarily involves some kind of generalized driving algorithm but more usefully, it gives you a clear goal and distribution to measure against.

The defined ODD is essentially cherry-picking the routes.

Sure, if the powerset of all roads in a major city is "cherry-picking" to you. The rest of us just call that driving.

Waymo works perfectly fine in the rain. No driver.
