Investors wanted more details on Tesla's robotaxi plans, but the Cybercab update left them wanting, triggering a sell-off.

The next-gen robotaxi's first public rule is an adult-only age floor, and it rewrites the near-term family-use case for autonomous transit.

Tesla published a form Thursday soliciting interest in Cybercab fleet purchasing - a signal it's moving toward commercial robotaxi operations.

Ahead of Tesla's Cybercab launch, Waymo publicly warns that vision-only, end-to-end AI systems can't cut it for full autonomy.

Investors are betting on a regulatory breakthrough as Tesla edges closer to a robotaxi without manual controls - here's what it means for the EV maker's valuation and the autonomous driving race.
