The group, which by its own account “fight for car-free spaces, transit equity and the end of car dominance”, believes “people, community and park space must be prioritised over polluting, dangerous and murderous vehicles”.

Earlier this week, as part of its “Week of Cone”-campaign, a Tik Tok video posted by the group went viral. In the video, the group encourages its followers, who are opposed to autonomous vehicles (AVs), to start placing the city’s many orange traffic cones on their hoods to disable them.

Over and above being a protest, it is also a way to highlight an important decision by the state regulator on whether to significantly expand robo-taxi services that were due to be made on July 13. This has been delayed until August 10, and Safe Street Rebel believes the delay is a sign of the success of the campaign.

The San Francisco Standard reported that the cones immobilise the autonomous vehicles by forcing them into “shutdown mode” with their hazard lights on, “until the cone is removed, or a company technician comes to reset the car’s system”.

For a substantial amount of time, Google’s Waymo and GM’s Cruise AVs have been causing havoc on the streets of San Francisco, including incidents where the vehicles interfered with emergency response teams and the killing of a dog.

Concerned activists also feel the AVs have become a new form of ubiquitous surveillance to aid the police department.
