Waymo's raison d'etre within Alphabet is that they solved self driving. They need to show Alphabet that they can deploy self driving at scale. Unfortunately, they only solved the problem when the car is supervised by a remote driver. Which is more expensive than hiring a human to drive a stock car. So they keep saying they're expanding the service without actually deploying at scale in the hope of postponing the inevitable moment at which Alphabet's board will realize that it's been taken for a ride.
