Tesla CEO Elon Musk said on Thursday the company has launched its ride-hailing service in San Francisco's Bay Area, but did not clarify whether it is using self-driving vehicles.

However, unlike Austin, where a safety monitor is sitting in the front passenger seat, San Francisco Robotaxis have a safety driver behind the steering wheel. This is due to Tesla not having all the regulatory approvals required by the state of California to offer paid driverless taxi rides.

Tesla’s Robotaxi app is now displaying availability for rides across much of the San Francisco Bay Area. The map of a geofenced zone where rides are possible spans the region from just north of the Golden Gate Bridge to San Jose.
