Several of Waymo’s autonomous vehicles were seen stuck in the middle of San Francisco streets following a significant power outage that took out the city’s traffic lights. Waymo responded to the power outage by suspending its ride-hailing services in the city, but images and videos on social media showed the self-driving taxis stopped at intersections with hazard lights on.
“We have temporarily suspended our ride-hailing services in the San Francisco Bay Area due to the widespread power outage,” Suzanne Philion, a spokesperson for Waymo, told Engadget in an email. “Our teams are working diligently and in close coordination with city officials, and we are hopeful to bring our services back online soon.”
Honestly, I’m happy they picked this as a default “car doesn’t know what to do” scenario. From what I’ve seen Tesla’s default is to just ignore the unknown thing, I wouldn’t be surprised if Robotaxis would have just treated all the blank lights as green.
It can be tough not to. Earlier this fall I was out of town and drover through an intersection before realizing no there was a traffic light there. Since it was night and the light was out, I had no reason to expect one so I effectively treated it like a green light.
I’m probably not the only one: next time I went past that intersection the city had placed cones and temporary stop signs
What’s the default on regular drivers when the traffic lights are not working?
The default at least in most of the US, is to treat a malfunctioning light as an all-way stop sign, with traffic alternating in each direction. The waymos instead stopped and blocked intersections, failing to reach the basic expectation for human drivers. Should we not hold these machines to a higher standard, if not at least the same standard as human drivers? Self-driving vehicles are supposed to be safer and ‘better’ than human drivers.
An intersection with the lights no longer working is treated as a stop sign.
I admit I scratch my head at 4 way intersections with blinking yellows on all 4 though. Usually the bigger road gets the yellows for caution, the adjacent lanes have to yield.
I’ve not seen an intersection with four blinking yellow lights in California; typically two ways are blinking yellow (caution) and the other two are blinking red (stop).
I’ve seen both. Places where the lights are only intended to work at busy hours default to flashing red and flashing yellow. Lights with a power outage can be random but I’ve also seen flashing yellow in all directions. I don’t know why that’s even an allowed configuration though
Yeah the few times I’ve seen them set like that everyone is stopped, and just kinda waving people to go. I think it’s to do with power outage, and tye place I’ve seen it twice is a 4x3 lane intersection.
I’ll give you the benefit of the doubt and assume you don’t drive.
A LOT of drivers actually don’t know the answer to this one!
Most humans can learn on the fly though. If they see people taking turns at a broken stoplight they’re likely to follow that example.
Another option is, there are more than one country on earth.
I’m not American
My first assumption giving them the benefit of the doubt would be that it’s a rhetorical question to point out that there is a proper response and the car should have been taught to do that instead. Even if a lot of actual drivers don’t know the answer.
