Armed with traffic cones, protesters are immobilizing driverless cars

An anonymous activist group called Safe Street Rebel is responsible for this so-called coning incident and dozens of others over the past few months. Over the past couple of years, driverless cars have become ubiquitous throughout San Francisco. Coning driverless cars fits in line with a long history of protests against the impact of the tech industry on San Francisco. "We thought that putting cones on these [driverless cars] was a funny image that could captivate people," says one organizer. "We don't really need traffic cones to show how vulnerable they are," says the Safe Street Rebel organizer.
