Google says it bears some responsibility for first accident caused by self-driving car

One of Google's self-driving cars hit a public bus last month while it was in autonomous mode on a Mountain View, California, road

The collision occurred on Valentine's Day and Google reported it to California's Department of Motor Vehicles in an accident report that the agency posted Monday. Though not the first time one of Google's self-driving cars has been involved in an accident, it is the first time one of Google's cars has caused the accident.

The DMV report doesn't address fault, but Google has said it is at least partially responsible for the incident.
