The Economics of Robot Taxi Service

No one company has successfully demonstrated a mastery of all the dimensions of launching a viable robot taxi service anywhere except Waymo and Phoenix. And there the last frontier is the economics. We don't know if it's possible to operate one city profitably, but not another. So just, but it feels like it leaves us waiting for the technological miracle, which I think is what a lot of investors have wanted out of a BTAC for a long time.
