Waymo, owned by Google's parent company Alphabet, is rolling out driverless cars to passengers in L.A. San Francisco and Phoenix already have them.

After rapidly expanding its self-driving car program, things took a disastrous turn for Cruise when one of its robotaxis struck a pedestrian.

The state issued the immediate suspension of the self-driving cars after one struck a pedestrian.

Historians say that a little more than a century ago, when cars first hit the roads, they caused nervous laughter and raised real concerns, much like driverless vehicles today.

Self-driving cars have flooded San Francisco's streets, and not everyone is happy. Street activists have been using a low-tech solution to incapacitate the vehicles.

In a 3-1 vote, California's transportation regulator allows self-driving car companies to expand their programs in the state — despite opposition from police and fire departments.

Regulators gave the Cruise service approval to charge passengers for driverless rides, a first for the state. Initially, the service will be available at night in less congested parts of the city.
