Activists putting cones on the hoods of self-driving cars to stop them in San Francisco

Activists in San Francisco have come with a new, yet simple, way to stop driverless cars after deadly incidents and headaches caused by autonomous vehicles. The campaign is timed to coincide with the California public utilities commission's vote to expand driverless car services. Cruise also argued its cars have not been involved in a single fatality or serious injury after accumulating 3 million miles on San Francisco streets. Autonomous car expert Billy Riggs of the University of San Francisco told KTVU that data shows driverless cars are safer than human drivers. That's one of the reasons Cruise's newly approved driverless service in San Francisco is being so tightly controlled.
