Protesters develop novel way to build cone-sensus against driverless cars

San Francisco's Safe Street Rebel group are disabling autonomous taxis by placing a cone on the hood of the car

A group of San Francisco organizers are encouraging people to put traffic cones on the hoods of driverless vehicles as a form of protest against the cars' expansion on city streets.

A video of the group's actions with step-by-step instructions on how to disable a robo-taxi with a cone has gone viral on Twitter and sparked intense debates about the pros and cons of autonomous vehicles and the value of protesting in this way.
