A group of activists in San Francisco have begun stopping driverless cars from travelling around the city by putting traffic cones on the bonnets of cars.
Pedestrian safety group Safe Street Rebel have posted a video of them stopping the vehicles in a simple way.
They claim driverless taxis pose dangers and are pushing their campaign before a vote in California on the issue this week.
The video gives step-by-step instructions on how to disable a driverless vehicle.
