Not because a bunch of cars that are perfectly capable of moving are just sitting there blocking things purposefully waiting for the driver in the sky to take over.
And what if, due to $BIG_DISASTER they won’t be able to for a week?
(Not an argument against Waymo doing better in this situation though!)
Not so much police cars, anymore.
Back in the time of the B-Body Caprice and the Crown Vic, sure. These days with the exception of the Tahoe the most common police vehicles are all unibody platforms. Charger, Durango, Explorer, Taurus, and the rare Australian Caprice
You can still bolt a push bumper to them and most departments do, but they have to be used with a lot more caution and a lot less aggression to avoid damaging the vehicle than in the days of body-on-frame sedans.
Fire trucks on the other hand, yeah they're basically the opposite in that there might be a couple of Explorers or Durangos in the fleet but most everything else is a medium duty truck or a custom chassis specifically for fire service.
Yes that’s the correct decision when those are the only options, like if a car has stalled or the driver just got out and ran away.
In this case there’s a third option: the computer that’s still perfectly functional should have been able to get out of the way on its own. And legally all drivers are required to.
I assume that applies to robots as well, if it doesn’t it absolutely should.
Pretty sure that's always the expectation? It's typical to tow illegally parked cars, smash windows to run hoses through cars blocking hydrants, etc.
The only unusual thing here would be holding a corporation to account the way we hold individuals to account.
don't be a dick, don't block the road
Chances are the damage will be solely on your vehicle, as fire trucks and police vehicles are equipped to push stuff off the road without damage to their equipment.
Were any emergency vehicles actually blocked?
We have an actual failure here–step one is identifying actual failures so we can distinguish what really happened from what hypothetically could.
They need to drive or pull over. Never just stop there in the road and wait.
They're not. But it's also not a disaster. Pretending it is on Twitter is pandering, not policymaking.
> They need to drive or pull over. Never just stop there in the road and wait
Agreed. Waymo has a lesson to learn from. Sacramento, and the NHTSA, similarly, need to draw up emergency minimums for self-driving cars.
There are productive responses to this episode. None of them involve flipping out on X.
Because it’s a power outage. If we instead learned about this during a real disaster people could have died because these things were let on the road without planning what they should do in abnormal circumstances.
We’re lucky it’s not a disaster.
This is universally true. The question is how bad could it have been, and in which cases would it have been the worst?
> We’re lucky it’s not a disaster
This is always true. Again, the question is how lucky?
We have an opportunity to count blocked emergency vehicles and calculate a hypothetical body count. This lets us characterize the damage. But it also permits constraining hysteria.
I'm sure that if this was something predictable like a cyclone or wildfire, Waymo would still have 100% of their nightly traffic on the road, right? And SFFD would not be able to do what they normally do when they can't get support, which is hop into the car and use the controls to manually move it?
Or... maybe Waymo HAS considered what their cars should do in abnormal circumstances and this kind of outcome was considered acceptable for the number of cars and the nature of the "disaster"?
They are. I did myself yesterday because one was sitting at the front of a turning lane at a dead light, just waiting there forever with the blinker on.
At what point can we be spared from having Waymos lessons inflicted upon us
Again, we had a real event happen. Not hypothetical. What was the actual cost inflicted?
Until "Waymos lessons" are killing people at that rate, I am 100% OK with a Waymo making my trips an extra 5 minutes longer every 50th trip or whatever else the real stat is.
I was curious if Waymo has even been involved with a crash that killed someone, so I looked it up. The answer is yes - there was a Tesla going 98mph in SoMa whose driver died after hitting a Waymo. Clearly the Waymo's fault!
Sure, but it would be notable if one had to. If none had to, we have a problem to solve, not a catastrophe.
There is a chorus of voices here on HN that have tried to do this openly, obviously, myself included. It seems to be almost universally derided by people who apparently assume that we're just trying to hurt a start up out of anti-environmental sentiment and jealousy.
There are more ways to get "self-driving cars" wrong than there are to get it right. Driving is far more complex than the hackers here on Hacker News seem to want to concede, and even if that wasn't the case, I'm not sure where the sentiment that a trillion dollar corporation is naturally going to implement this system with the best interests of society in hand comes from.
It's a genuine frustration here.
I believe the answer is far more complicated than it seems and in practice having the cars stay still might have been the safest option any of the parties could agree on (Waymo's office, the city traffic people, state regulators, etc).
There are people thinking this stuff out and those cars can 100% pull over automatically but an explicit choice was made not to do so for safety.
Look I like Waymo. I think they’re neat and I trust them far more than any of the other companies. But in my mind being able to handle stuff like this is just a requirement to be on the roads in any non-trivial number. Like if they had two vehicles in this happened then OK that’s a problem but it was two vehicles in an entire city.
When you have enough on the road that you can randomly have six at one intersection you should absolutely be able to handle this by then.
I want them to do good. I want them to succeed. But just like airliners this is the kind of thing where people’s safety comes first.
What we saw happen looks like the safety of the Waymo and its passengers came above everyone else despite having no need to do that. There are certainly some situations where just staying put is the best decision.
The power went out and there are no other hazards on the road is not one of them. They made things worse for everyone else on average in a foreseeable situation where it was totally unnecessary. And that’s not OK with me.
This feels like the kind of thing that absolutely should’ve been tested extremely well by now. Before they were allowed to drive in large volumes.
One driver doesn’t know how to handle a power outage? It’s not news. Hundreds of automated vehicles all experience the same failure? National news.
I wish the Waymos handled it better, yes, but I think that the failure state they took is preferable to the alternative.
And "don't blow through an intersection with dead lights" is super easy to program. That's not enough for me to forgive them of all that much misbehavior.
What?!? We’re talking about autonomous vehicles here.
I don't know if waymos are programmed for that and it could very well be that there were so many pedestrian crossing it wouldn't apply it anyway.
That's not how any of this works. You can anthropomorphize all you like, but they don't "know" things. They're only able to predictably respond to their training data. A blackout scenario is not in the training data.
Is there anyway to read more about this? I'm skeptical that there aren't any human coded traffic laws in the Waymo software stack, and it just infers everything from "training data".
And the usual setup of an autonomous car is an object recognition system feeding into a rules system. If the object recognition system says an object is there, and that object is there, that's good enough to call "knowing" for the purpose of talking about what the cars should do.
Or to phrase things entirely differently: Finding lights is one of the easy parts. It's basically a solved problem. Cutting your speed when there isn't a green or yellow light is table stakes. These cars earn 2 good boy points for that, and lose 30 for blocking the road.
Compared to the overall self-driving problem which is very much not a super easy problem.
1: streetlight with no lights
2: streetlight with blinking red
2.5: streetlight with blinking yellow
Then they are 100% not qualified to be on the road. Those are basic situations and incredibly easy to replicate, simulate, and incorporate into the training data.That is to say, they are not edge cases.
Dealing with other drivers in those settings is much harder to do but that's a different problem and you should be simulating your car in a wide variety of other driver dynamics. From everyone being very nice to everyone being hyper aggressive and the full spectrum in between.
It's a tough question. The entire reason I'm defending this shortcoming is exactly that I prefer the fail-safe shutdown to any attempt to navigate bizarre, barely conforming to traffic code, blacked out intersections that are inherently dangerous.
No one was injured this time but that's a huge assumption on your part
I honestly wish the human drivers blowing through intersections that night would have done the same. It's miracle no one was killed.
>I honestly wish the human drivers blowing through intersections that night would have done the same. It's miracle no one was killed.
A bit deflective, huh?
Imagine a model that works real well for detecting cars and adults but routinely misses children; you could end up with cars that are 1/10th as deadly to adults but 2x as deadly to children. Yes, in this hypothetical it saves lives overall, but is it actually a societal good? In some ways yes, in some ways it should never be allowed on any roads at all. It’s one of the reasons aggregated metrics on safety are so important to scrutinize.
Whatever, it happens.
This was a (totally unintentional) coordinated screw up causing problems all over as opposed to one small spot.
The scale makes all the difference.
Eg. if they see 5 cars going around them and "solving" the intersection, do they get empowered to do the same? Or do some annoying honkers behind them make them bite the bullet and try their hand at passing it (and not to worry, other drivers will also make sure no harm comes to anyone even if you make a small mistake)? Human drivers, no matter how inexperienced, will learn on the spot. Self-driving vehicles can "learn" back in the SW department.
Yes, driving is a collaborative activity which requires that we all partner on finding most efficient patterns of traffic when traffic lights fail. Self-driving cars cannot learn on the spot, and this is the main difference between them and humans: you either have them trained on every situation, or they go into weird failure modes like this.
It's all a careful risk calculation, those self driving cars need to determine if it's safe to continue through an intersection without the traffic lights their computers spent millions of hours to train on (likewise with humans). That's a tough choice for a highly regulated/insured company running thousands of cars.
If anything, their programming should only take such a risk to move out of the way for a fire truck/ambulance.
Would would they do that? It's a hive, isn't it?
How many non-Waymo accidents happened at intersections during this time? I suspect more than zero given my experiences with other drivers when traffic lights go off. Apparently, Waymo's numbers are zero so humans are gonna lose this one.
The problem here is that safety and throughput are at odds. Waymo chose safety while most drivers chose throughput. Had Waymo been more aggressive and gotten into an accident because it wouldn't give way, we'd have headlines about that, too.
The biggest obstacle to self-driving is the fact that a lot of driving consists of knowing when to break the law.
Did they? They chose their safety. I suspect the net effect of their behavior made the safety of everyone worse.
They did such a bad job of handling it people had to go around them, making things less safe.
We know what people are like. Not everyone is OK doing 2-3 mph for extended time waiting for a Waymo to feel “safe”.
Operating in a way that causes large numbers of other drivers to feel the need to bypass you is fundamentally worse.
There is no viable choice other than prioritizing the safety of your rider. Anything less would be grounds for both lawsuits and reputational death.
The fact that everybody else chose throughput over safety is not the fault of Waymo.
Will you also complain when enough Waymo cars start running on the freeways that a couple of them in a row can effectively enforce following distances and speed limits, for example?
Something I had pounded into me when I drove too slowly and cautiously during my first driving test, and failed.
Those Waymos weren't moving which is a pretty egregious example of obstructing traffic.
An old rule of thumb is every time a service expands by an order of magnitude there are new problems to solve. I suspect and hope this is just Waymo getting to one of those points with new problems to solve, and they will find a way to more graciously handle this in the future.
In my state, that would itself be a traffic violation, so yes I would. The leftmost lane on an interstate highway is reserved for passing. An autonomous vehicle cruising in that lane (regardless of speed) would therefore be programmed in a way that deliberately violates this law.
Enforcement is its own challenge, whether robots or humans.
Sadly, in most states, this is not true anymore. Most of those laws have been repealed.
I was very pleasantly surprised when I was in Colorado that they had explicit signs saying that if you had 5 (I think) or more cars behind you that you were supposed to pull right and let them pass.
However, I wasn't really thinking about a Waymo cruising in the left lane but simply 4 or 5 Waymo's in the right lane going right at the speed limit with proper following distance. That's going to effectively lock the right lane to the speed limit which then means that even a single other car would lock the left lane to the speed limit as well. Basically, even a couple of Waymos in the right lane would drop freeway speeds dramatically.
Surprisingly it seems to even be moderately enforced these days even in Minnesota, which I’d have bet money on never happening since it’s a state pastime to play passive aggressive traffic cop for many.
https://www.reddit.com/r/coolguides/comments/1fuw97s/a_cool_...
Perhaps not the most trusted source on the matter, but at a glance it seems more or less the vast majority of states have laws that effectively “ban” slow moving traffic in the left lane from impeding traffic. Enforcement I’m sure will be all over the map - likely down to even a county level within individual states.
While I do wish all states were “purple” or above in that map, the situation seems largely up to how state patrol and other agencies want to enforce it.
I’ve seen it enforced now with my own two eyes in KY, WI, MN, and IL.
So, you're saying Waymo can't handle a regular 4 way stop sign given how everyone else on the road drives? That's not a problem?
When traffic lights go out, that is supposed to be a 4 way stop with appropriate yielding of right-of-way. The problem is that most human drivers can't deal with even a simple, low-traffic stop sign 4-way-stop reliably, and these are complex 4-way-stops with lots of right-of-way changes when power is off.
For example, navigating intersections in San Diego during the blackout was a disaster with lots of accidents and that long predated Waymo.
> but an explicit choice was made not to do so for safety.
You know this how?
However even if that’s not true if they have more cars than human drivers there’s gonna be a problem until they work through the queue. And the bigger that ratio, the longer it will take.
Self-driving cars should (1) know how to handle stops, and (2) know that the rules for a failed traffic light (or one flashing red) are those for an all-way stop.
Humans, luckily, never follow the rules to the letter, which made it reasonable to put them down like this: some will be more impatient/aggressive, others will establish eye contact and wave one another through, etc.
In a situation like this where you've got "drivers" who can't collaborate and learn on the spot, the rule does not make sense.
The first arrived rule (which applies before yield right) is usually unambiguous in a traffic jam situation (since it will also be the position where the last car went the least recently, and everyone at the intersection will have been close enough to see through the prior cycle.)
I apply the alternating pattern even when I have right of way to keep the traffic flowing.
Just pulling over and getting out of the way really would help. There's no reason a human couldn't do the same safely. Not beta testing your cards on public roads would really be ideal. Especially without human drivers ready to take over.
Unfortunately HN is still not ready for that discussion despite the year being 2026 in a few days.
The sentiment comes from the corporation itself. With this much money at stake you know they have a hand in steering the conversation and that includes on sites such as this.
Maybe I'm reading things wrong, but it sounds like the top comment wants waymo to be better, and you want waymo to be off the roads. You're not talking about the same kind of "thinking through the ramifications".
I feel like self-driving cars are, pretty objectively, the single least environmentally friendly mass transit solution (more cars being made and using more rare-earth minerals to produce them, more cars being driven rather than increasing public transit usage). What's the argument that not liking self-driving cars is "anti-environmental"?
And I believe Waymo remote access only allows providing high level instructions (like pull over, take the next right, go around this car, etc) precisely because full direct control with a highly and variably latent system is very hard/dangerous.
And in an emergency situation you’re likely to have terrible connectivity AND high level commands are unlikely to be sufficient for the complexity of the situation.
Perhaps in such cases they can pull over in a safe place, or if they have an occupant ask them if they wish to continue the journey or stop.
Perhaps they already do this, I have no experience with autonomous vehicles.
Decades ago I recall talking to a fireman expressing a question of what happened if there was a car blocking their access in an emergency and he made it clear that the bumper on the front of the truck and the truck's healthy diesel engine would usually take care of the problem very quickly.
The basic thing is to treat everything like a four-way stop sign.
This has been the MO for "tech companies" for the past 20 years. Meanwhile I'm told I'm paranoid when the industry of "move fast or break things" decides to move into mission/safety critical industries and use its massive wealth to lobby for deregulation to maintain its habits.
We certainly have BS regulations done to constrain competition. But I'd wager a good 80% of them exist for good reason.
“Thought of the day, and I wish there were a way to get this to legislators:
Come the next Big One earthquake, all of San Francisco’s emergency services will be blocked by Waymos.”
I’m AMAZED they’re not designed to handle this better. This does indeed seem like a massive problem. “Oops we give up” right when things get the worst? How is this OK?
I’ve been very impressed by Waymo’s more cautious approach. Perhaps they haven’t fully thought through the ramifications of it though.
