Uber's self-driving car program stopped in California

Uber started a pilot driverless-car program in the San Francisco area, but California regulators are putting a stop to it.

Uber announced Wednesday that it will deploy a small fleet of driverless Volvo XC-90 SUVs in San Francisco.

The pilot program will allow riders to experience the cars as Uber works to identify glitches before expanding the technology's use in San Francisco and elsewhere.

However, the state says that Uber must stop self-driving car service in the area until it gets state permit.

California law requires a test permit for "autonomous vehicles."
