Matier on the SF incident that may have caused Cruise's nationwide vehicle recall

Cruise is recalling all its self-driving vehicles nationwide following an accident in San Francisco last month. It started when a hit-and-run driver struck a woman who was walking south of Market St., throwing her into the path of the Cruise vehicle. Instead of coming to a stop, the vehicle did as programmed and pulled over, dragging the woman with it. KCBS Radio news anchor Patti Reising spoke with KCBS insider Phil Matier for more.
