Self-driving cars are supposed to improve safety on roadways because they have all sorts of sensors and gadgets to help them avoid accidents. But, it's hard for us to know whether that's true or not because not much is known about self-driving car accidents.
Since September of last year, three self-driving test cars from Google and one test car from Delphi Automotive have been involved in minor accidents in California. According to Chicago Tribune, two of those accidents occurred while the cars were in self-driving mode.
Google and Delphi said their cars were not at fault in any accidents, which the companies said were minor.
Beyond that, they're not saying much. Both the companies making the cars and the California Department of Motor Vehicles are staying mostly mum on the subject and that's a problem.
The fact that neither the companies nor the state have revealed the accidents troubles some who say the public should have information to monitor the rollout of technology that its own developers acknowledge is imperfect.
