SF Residents Disable Autonomous Vehicles With Traffic Cones

San Francisco has become a hub for companies wanting to test autonomous vehicles thanks to its progressive leadership and proximity to Silicon Valley. But local residents have slowly been losing patience with the vehicles themselves as they’ve grown in number. While malfunctioning AVs are never popular with other drivers, allowing them to operate without a human safety driver has resulted in rolling reports of vehicles clogging up traffic.

Self-driving test mules are programmed to exercise the maximum amount of caution whenever they’re uncertain of how to progress. This has resulted in traffic jams that are infuriating the locals. But it has also made them incredibly easy to defeat, with activist groups leveraging their circumspect behavior to disable them by placing a traffic cone on the hood.


The California Public Utilities Commission (CPUC) is expected to approve the expansion of both Cruise’s and Waymo’s autonomous vehicle passenger service deployments later this month. While the California Department of Motor Vehicles has enjoyed a contentious relationship with the brands, by previously disallowed autonomous vehicle deployment permits and being involved in a lawsuit after trying to make corporate crash data public, the DMV has also been under pressure to be kind to AV firms and allow them to operate test vehicles in select cities.


But reports have cited a growing sense of unease among local residents and select city agencies. Cabbies and Uber drivers have long despised the concept of robotaxis and they’re now starting to be joined by aspects of the local transit authority, emergency response personnel, and even San Francisco construction workers — who are now pressuring the city to scale back its allowance on autonomous test vehicles and provide guidelines that would keep them off the streets during periods of heavy traffic.


The reason has everything to do with their being inconvenienced. Over the past few years, videos have been released of self-driving cars interfering with city buses or holding up traffic when they encounter construction sites. We’ve likewise seen reports of vehicles getting into accidents, calling into question how roadworthy their systems actually are.

Police have even issued warrants to obtain video footage captured by autonomous vehicles operating in San Francisco and Arizona's Maricopa County. This is being done under the auspices of solving crimes and has locals feeling a little nervous about their privacy as their neighborhoods are turned into a corporate-funded surveillance state.


While being carted around by self-driving vehicles is a truly novel experience, the practice has opened places like San Francisco up to a host of new traffic issues that have inspired locals to petition the government to think twice about issuing permits. But progress has been slow and there are hundreds of vehicles already in operation — encouraging activists to take matters into their own hands.


A group called Safe Street Rebel has created the “ Week of Cone,” using social media to encourage citizens to disable Waymo and Cruise vehicles testing in San Francisco. The videos explain how AVs will effectively stop moving if someone places any relatively large object on their hood and recommends using traffic cones as the perfect option — as they’re readily available and unlikely to do any permanent damage to the cars.


Though the activists do make for some unlikely allies, as they’re not all that keen on automobiles in general. Safe Street Rebel describes itself as fighting for “car-free spaces, transit equity, and the end of car dominance.” It wants fewer vehicles on the road to make way for more bicycles, public parks, and lessened pollution. It’s also worried about “traffic violence” (car accidents) and is a major advocate for Vision Zero campaigns championed by city officials who want to promise a future where roadway injuries are made impossible.


Most proposals involve adding bike lanes, lowering speed limits, enhancing traffic enforcement efforts, expanding public transit options, and barring passenger vehicles from certain areas. There’s also a community outreach element designed to get the public on their side and a push to reduce vehicle ownership rates under the assumption that it would be better for the environment. They’re the traditional automotive enthusiast’s natural enemy. But they’ve elected to go after autonomous vehicles, creating some overlap with a subset of drivers who have absolutely had it with self-driving test mules.

The group has been sharing photos and clips of people disabling AVs on TikTok, Instagram, and Twitter over the last few days. Many include talk about how EVs (Waymo and Cruise both use all-electric fleets) pollute via contentious mining practices, level criticisms against self-driving vehicles that have held up SF public transportation or bike lanes, and note that the vehicles themselves lack accountability because there’s no human driver to receive a ticket. Some even call the vehicles “dog killers,” as there was an earlier incident where one AV fatally struck a small canine. There’s also been outrage over Waymo and Cruise allegedly working with the SFPD to hand over vehicle footage.


While the act of disabling AVs is unlikely to improve traffic flow. The frustration felt by locals having to circumvent a stalled test vehicle is valid and the response seems pretty measured. Safe Street Rebel isn’t encouraging people to damage vehicles. But disabling one with a traffic cone will force Waymo or Cruise to send out a technician and will draw an immense amount of public attention to how fallible modern AVs happen to be.


A spokesperson for Waymo told Road & Track that the company is not amused with the trend by stating “this understanding of how AVs operate [is not only] incorrect, but this is vandalism and encourages unsafe and disrespectful behavior on our roadways. We will notify law enforcement of any unwanted or unsafe interference of our vehicles on public roadways.”


We’re not sure what kind of offense someone would actually be charged with for interfering with an AV. But if you’re worried about that kind of thing, it may be easier to simply attend the California Public Utilities Commission meeting being held on July 13th to voice your concerns. Otherwise, it looks to be open season on San Francisco’s autonomous test fleets until they’re reissued human safety operators who could easily remove the cones.

    As revolutionary statement, this action hardly ranks with the Weathermen, or even the Abbie Hoffman "Steal this Book" anarchy but I do laud their tactics and goals. I always think to myself when reading of the autonomous car research "why"? But, like the wholesale rejection of TV phones after the 1964 World's Fair, the modern population has a completely different mindset than I have now.

    I saw that one of these whack-jobs MOs is to drive under the speed limit and hold up freeways!


    Which would just entice me to fit some sort of deployable bumper or some sort of device where I could deploy, then slowly move up until the device connects with the bumper of the offending vehicle, then hit the gas! (Bonus points if I can PIT them safely off the road to the left, where they'd suddenly find themselves seeing traffic flying by in the opposite direction as they'd be sitting on the shoulder facing against traffic, with the only injury being to their self-righteous egos! Hopefully, aforementioned dilettantes would stay in their mommy's basements, where they belong!)


    Then I think that I'd be tempted to do that EVERY TIME I come upon someone in the left lane not using their signals and staring at their phone, and yet following underposted numbers on a sign reading "SPEED LIMIT" with the fervor of followers of name-your-religion-of-choice on its highest holy day!


    And then I think how much I'd love to do that in Northwest Ohio, where this zealotry is even now a high art form, and I realize I'd just land in trouble in a hurry!

  • EBFlex Garbage but for less!
  • FreedMike I actually had a deal in place for a PHEV - a Mazda CX-90 - but it turned out to be too big to fit comfortably in my garage, thus making too difficult to charge, so I passed. But from that, I learned the Truth About PHEVs - they're a VERY niche product, and probably always be, because their use case is rather nebulous. Yes, you can run on EV power for 25-30 miles, plug it in at home on a slow charger, and the next day, you're ready to go again. Great in theory, but in practice, a) you still need a home charger, b) you paid a LOT more for the car than you would have for a standard hybrid, and c) you discover the nasty secret of PHEVs, which is that when they're on battery power, they're absolute pigs to drive. Meanwhile, to maintain its' piglike battery-only performance, it still needs to be charged, so you're running into all the (overstated) challenges that BEV owners have, with none of the performance that BEV owners like. To quote King George in "Hamilton": " Awesome. Wow." In the Mazda's case, the PHEV tech was used as a performance enhancer - which worked VERY nicely - but it's the only performance-oriented PHEV out there that doesn't have a Mercedes-level pricetag. So who's the ideal owner here? Far as I can tell, it's someone who doesn't mind doing his 25 mile daily commute in a car that's slow as f*ck, but also wants to take the car on long road trips that would be inconvenient in a BEV. Meanwhile, the MPG Uber Alles buyers are VERY cost conscious - thus the MPG Uber Alles thing - and won't be enthusiastic about spending thousands more to get similar mileage to a standard hybrid. That's why the Volt failed. The tech is great for a narrow slice of buyers, but I think the real star of the PHEV revival show is the same tax credits that many BEVs get.
  • RHD The speed limit was raised from 62.1 MPH to 68.3 MPH. It's a slight difference which will, more than anything, lower the fines for the guy caught going 140 KPH.
  • Msquare The argument for unlimited autobahns has historically been that lane discipline is a life-or-death thing instead of a suggestion. That and marketing cars designed for autobahn speeds gives German automakers an advantage even in places where you can't hope to reach such speeds. Not just because of enforcement, but because of road conditions. An old Honda commercial voiced by Burgess Meredith had an Accord going 110 mph. Burgess said, "At 110 miles per hour, we have found the Accord to be quiet and comfortable. At half that speed, you may find it to be twice as quiet and comfortable." That has sold Mercedes, BMW's and even Volkswagens for decades. The Green Party has been pushing for decades for a 100 km/h blanket limit for environmental reasons, with zero success.
  • Varezhka The upcoming mild-hybrid version (aka 500 Ibrida) can't come soon enough. Since the new 500e is based on the old Alfa Mito and Opel Adam platform (now renamed STLA City) you'd have thought they've developed the gas version together.
