In June, Cruise started operating its self-driving taxi service in San Francisco where it charges for rides in Chevrolet Bolt EVs that operate without a human safety driver. Cruise uses a fleet of 30 Bolts to ferry the paying passengers around parts of the city. Those Bolts are currently built at Orion Assembly plant in Orion Township.

Now the San Francisco-based Cruise, of which GM owns an 80% stake, will bring a driverless taxi fleet to Austin, Texas, and Phoenix, Arizona, in the next three months, Cruise CEO Kyle Vogt said Monday.

Initially, Cruise’s operations in Austin and Phoenix will be small to generate revenue, with a plan to scale up operations next year, Vogt told an audience at a Goldman Sachs conference Monday, where he also said Cruise aims to hit $1 billion in revenue by 2025, said Cruise spokeswoman Tiffany Testo.
