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."

I’m sorry, so besides not wanting to pay a person to drive the vehicle, the fuck does this service actually provide again?

It makes stonks go up

This is really bad. You need to have emergency service vehicles able to move around the city. Blocking road like that could mean life or death for some. Public road isn't some playground for doing beta testing. Waymo needs to be heavily fined for putting public at risk.

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.

[–] AA5B@lemmy.world 4 points 2 days ago

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

Police and firefighters would love to have an excuse to go demolition derby on these things I bet.

[–] naticus@lemmy.world 4 points 2 days ago (8 children)

They'd probably love to, but wouldn't. Lithium fires could make a bigger problem than slowly going around them.

As long as the car isn’t moving, this is the best thing they could do. Emergency vehicles can drive around cars that aren’t moving. There should be plenty of room in any intersection for multiple vehicles.

[–] AA5B@lemmy.world 7 points 2 days ago

It seems like one of the first things you’d want a self driving car to do is to pull over

[–] cheesybuddha@lemmy.world 1 points 2 days ago

Until it's multiple self driving cars getting stuck in that intersection

[–] Godnroc@lemmy.world 48 points 3 days ago (3 children)

Sure are a lot of things to account for with these self driving car things. It would probably be way easier if they were separate from pedestrians and maybe limited on where they can go.

Trains. I want them to just be trains.

I think the best solution is more self driving cars and more Generative AI.

Would you like some glue with that?

This is one of the many edge cases that I’ve been convinced will keep self driving cars from becoming mainstream unless/until true AGI is achieved.

A few years ago I stopped at a red light next to a construction site. I was watching the traffic light, so at first I didn't notice a cop at the construction site trying to wave me through the red light. He finally took a few steps towards me and yelled to get my attention. Only then did I realize he was waving me through, so I did just that. I seriously doubt any current self driving car would recognize a police officer (and not just a random pedestrian) that’s overriding the traffic signal like that.

Another edge case, coincidentally at the same intersection a few years earlier was when there was a car fully engulfed in flames as I drove up. I could hear sirens in the distance, and the cars in every direction were making sure to safely get out of the way of the approaching fire trucks. At least one or two cars cautiously crossed on the red to get out of the way. Again, I doubt any current self driving car would have navigated that situation anywhere nearly as well as a human.

[–] AA5B@lemmy.world 1 points 2 days ago

I almost tested that first example but was too slow. I had a one month free trial of self-driving and approached a similar construction site where I didn’t see the officer at first ….. thinking “I wonder what the car would do?”

Yea, so what was wrong with Taxis anyway? At least we regulated those

Is it brown people? It's brown people, isn't it?

I’m curious about what cloud service caused a couple of these cars to shit the bed. They’ve been designed to handle a lot of the compute locally. They can’t even been driven from a remote operator - the vehicle mostly troubleshoots sticky situations itself.

I can’t imagine this is the first time their fleet has encountered a traffic light that’s out or cell towers that’s are not responding. They do half a million rides a week in cities that have infrastructure blinking in and out of service constantly.

[–] IphtashuFitz@lemmy.world 22 points 3 days ago (6 children)

It wasn’t a cloud failure. The self driving cars are highly dependent on traffic lights being red/yellow/green. With the signals inoperative the cars don’t know what to do. Even if there were police officers directing traffic at intersections, the cars aren’t programmed to recognize & respond to them.

[–] grue@lemmy.world 17 points 3 days ago

Even if there were police officers directing traffic at intersections, the cars aren’t programmed to recognize & respond to them.

That by itself ought to automatically disqualify any such driverless car for use on public roads.

[–] Jesus_666@lemmy.world 8 points 2 days ago

Even ignoring the police officers, aren't there clear rules for what to do when traffic lights are turned off?

In Germany, an inactive traffic light means that traffic control reverts to any present traffic signs (stop/yield/priority road). If none are present, the default rules for entering an intersection apply (which in Germany are to yield to any traffic coming from your right).

All of those rules already must be implemented for autonomous driving so why the hell couldn't they implement a hierarchy?

[–] Ghostalmedia@lemmy.world 7 points 3 days ago

Weird. If that’s the case, how hasn’t this been more of an issue? This isn’t the first time a light has gone out in SF.

cell towers not responding definitely not a first time. happened years back because of a music festival, and there were like some dead cellular spots in san francisco that held them back a while back as well.
