Tesla's June launch of its long-awaited "robotaxi" requires a lot of qualifiers: it was supervised, open only to a few invitees and included somewhere between 10-20 vehicles. The stock jumped 8% the day after the launch, and some participants and observers called it a success. The shares have largely given back that gain since then.

The company has begun a test run of the driverless cabs, years after CEO Elon Musk vowed they would be on the road.

A week before Tesla's supposed robotaxi launch, Waymo adds 80 square miles to its LA and SF driverless taxi service areas.
