The automaker will focus on development of partially automated driver-assist systems for personal vehicles like its Super Cruise, which allows drivers to take their hands off the steering wheel.

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.
