Anecdotally, both from riding in them and walking/driving next to/around them, this feels obvious. They never get distracted. Sure, they sometimes make mistakes, but the mistakes are never "I didn't see that". They see better than humans in all cases (where they operate). They react faster than humans.

The one case where they hit a child, it was because the child jumped in front of the car. And they showed that they hit the child at a lower speed than a human would have because of the reaction time.

I would rather be in an area where only Waymo's are allowed than an area where they are banned.

Waymo saved my life in LA.

When I visited LA, I rode in a Waymo going the speed limit in the right lane on a very busy street. The Waymo approached an intersection where it had the right of way, when suddenly a car ignored its stop sign and drove into the road.

In less than a second, the Waymo moved into the left lane and kept going. I didn't even realize what was happening until after it was over.

Most human drivers would've t-boned the car at 50+ km/h. Maybe they would've braked and reduced the impact, which would be the right move. A human swerving probably would've overshot into oncoming traffic. Only a robot could've safely swerved into another lane and avoid the crash entirely.

Unfortunately, the Waymo only supported Spotify and did not work with my YouTube Music subscription, so I was listening to an advertisement at the time of my near-death experience. 4.5 stars overall.

This detail sent me, it's crazy that we can pay $25 to have a life saving robot take us across the city yet Spotify is going to blast ads at us the whole time for the sake of making an extra $0.18 (yes that's the actual number) per hour of listening time.

I think you're over-playing how decisively a Waymo will move and under-playing how decent the average human is.

I've ridden in Waymos. They don't exactly slap on the blinker and move at the limit of traction like someone about to miss their exit. If cut off they absolutely will go full brake rather than perform any sort of spicy lane change or turn.

Essentially, a meat driver was waiting at a stop sign to make a turn onto the main road. I was in a Waymo driving on the main road and did not have a stop sign.

When we were 10 meters away from the intersection, the meat driver suddenly started to enter the intersection. I have no idea why.

Full brake would've hit the other car in the driver's side door at 40 km/h.

To be fair, we are not provided with the sensors to swerve safely. If we had some sort of 360 constant recording in the car (on screen?) it would be safer for humans to swerve. Instead we have to move our head, which is cheaper but lacks info. That's why we now have rear cameras

You'll probably never forget that advertisement, which is an exciting business opportunity for Waymo.

They could partner with Spotify and other media content partners so that the Waymo can generate an adrenaline-rush near crash experience when a premium advertiser's ad is playing. /s (hopefully)

I hope you are misremembering. Swerving is most often the wrong choice, and I would be disappointed if Waymo were opting for that. By far the best option is to panic stop. Human or robot, physics is a harsh mistress and swerving is more likely to make you lose control and end up in a much more unforgiving wreck.

It wasn't possible to stop at the speed the Waymo was moving at.

The Waymo didn't have the stop sign, the other driver did, at a three way intersection.

The other driver decided to suddenly enter the intersection, when the Waymo was like 5-10 meters away. This was after having stopped at the stop sign.

Either they weren't looking or intentionally trying to cause an accident. Swerving prevented the Waymo from crashing at 40 km/h into the driver's door.

The optimally regulated system doesn't know the road conditions that well. When the road surface is more slippery, it has the most profound effect on lateral friction, way more than braking.

The Waymo driver can measure the speed and the acceleration of the offending car and calculate, within at most tens of ms, its range of likely future trajectories. And it can calculate its own likely trajectories under maximum braking. And it can track exactly where all obstacles are that would matter if it swerves. All at once. And it can execute that emergency lane change with the control input that is least likely to cause a loss of control and most likely to successfully avoid the other car. It even has processing power to spare to keep playing that Spotify ad!

This depends a huge amount on car, driver and situation. It was the right advice for a learner driver in the 90s with no stability control, no experience and no side airbags, because if you’re going to hit something, hitting it front on is the least risky way. I’m not convinced it’s the right advice for a competent driver in a modern vehicle.
reply
rootusrootus

[-]
It is still standard advice today, as far as I know. Tires are better, stability control is better, but all else being equal you are still much more dynamically stable and have a lot more friction with the road when the car is stopping in a straight line than when swerving.

Also, in the case of someone running a stop sign, it is far from a sure bet they are going to hit their brakes at all, so by swerving you increase the odds that you will still hit them, but now it will be while you have exhausted all your adhesion on lateral control. So now instead of a front end collision with all the benefits of airbags and crumple zones, you are at a significant risk of rolling the car or spinning off the road and hitting something immovable with a part of your car lacking crumple zones.

The common mistake is people swerve and brake, which is a terrible combination - you should accelerate through a sudden manoeuvre, as it maintains control through it, much as you should accelerate through corners in general.

Absolutely. I was recently driving on a motorway in Portugal when a boulder (giant chunk of granite, 10+ tonnes) fell off the back of a truck - right in front of us, in a heavily laden (7 pax and luggage) car. Immediate massive cloud of dust, I checked my blind spot, veered across two lanes, and continued our journey, unscathed. I looked in the rear view, to see the car behind us jump on the brakes instead of evading. They caught the boulder.

Nobody killed, according to the news, but several taken to hospital in critical condition.

Oh, I say unscathed but our tyre exploded the next day, as apparently we caught a fragment, and again, that’s not a “slam on the brakes” moment, but rather “trundle to a stop on the shoulder and walk to the conveniently nearby tyre shop”.

The one case where they hit a kid, they should have been driving slower to begin with. Their stopping distance exceeded their visibility in a school zone during pickup time. They might have done better than a bad human driver, and had good reflexes on the brakes, but a good human driver would have evaluated the conditions and not have been going that fast.

Waymo as a system has crossed the threshold where I trust them more than average driver, but all this hardware is relatively new, well maintained, and their software is closely tied to it.

I’m way less confident of self driving in the hands of the general public when differed maintenance often results in people and even companies driving with squealing breaks and balding tires etc.

Not tightly coupled in obvious ways, but as I understand it they aren’t putting it on pickup trucks, convertibles, or anything toeing a boat etc. Their vehicles don’t have aftermarket suspension systems dramatically changing handling characteristics, or turned one into a stretched limo etc.

Which means the software can safely assume the vehicle will behave within a relatively narrow operating range.

I suppose owners will be motivated to have the thing do the driving (and so seek defeat devices and such), but at least the software can have "do nothing" as a safety mode if it manages to detect that the vehicle is not configured as expected.

And maybe the software can be designed to be coupled to a vehicle dynamics model that can be updated.

I don't think the vehicle performance really matters in the typical case. They're using like 20% of what the vehicle "can" do. They're probably hedging against the long tail of variance on the road somehow.

There is also a different kind of increased safety. There is no driver. No weird conversations about slaughtering goats, no sexual advances. No worrying that your driver is going to assault you or attempt to kidnap you. I know, it's all very far fetched, and Uber/Lyft drivers are almost always nice, courteous and professional, but I have experienced a few times when that hasn't been the case. With Waymo, it's not even an issue.

There are also new risks that weren't possible before. A software error can send you into oncoming traffic. Hackers can gain control of your vehicle either directly/remotely or by cleverly designed signage placed on the roadside. A disgruntled waymo contractor in the Philippines can remote drive you into a crowd of people. A flashing stoplight can leave you stranded at an intersection. The car may not see or react appropriately any number of uncommon hazards that human drivers would recognize and avoid. Only a relatively small number of these cars have been on the road, in limited conditions, and only for a small number years. There will be failures and risks we haven't even imagined yet.

Blaming the kid here is absurd. The kid lives in a system where pedestrians are second class citizens in a world dictated by the auto-petro industrial complex. An industry that has co-opted unelected traffic "engineer" in the US and completely changed the way we live for the last 70 years and have made Americans fatter and less connected.

If the child lived in a neighborhood where cars went slower (it was a 25mph zone) he wouldn't have gotten hit in the first place. Praising Waymo here is like praising a priest for not molesting a child. Yes it's good that the waymo slowed down more than the average car, but really the whole system should be completely rethought. Instead, we're pouring billions into single occupancy vehicles, when we should've been pouring billions into high speed rail, subways, etc.

I'm hopeful that waymos converge on a more efficient design and improve cities in general. As it stands, they are a way for the rich to commute without having to exchange pleasantries with the underclass.

What you're talking about has nothing to do with Waymo at all though. It's ostensibly off topic here. You're talking about car culture in general.

Yes, I blame the parents or the adults that were supposed to supervise the child (but not the child). I teach my kids not to run into the street. I also watch them like a hawk near streets because kids are dumb.

I agree with you that we have too strong of a car culture. But we do. So until that changes, we need to teach our kids and adults to be vigilant.

But while we do that, I'd still rather have Waymos around than human drivers.

I've been observing their behavior in Atlanta for about the past year. Our roads here are fairly curvy, hilly, and lacking of expected markings, yet I haven't seen a driverless Waymo vehicle make a single odd move. One thing that brought a smile to my face was when I came to a 4-way stop at the same time as a Waymo vehicle at night & I flash my brights to tell the other vehicle to go ahead (southern hospitality) and I see the Waymo immediately begin its course through the intersection. I was so jolted that I began to tail it in order to pull up next to it to see if there was a human behind the wheel. Watching it drive down this slowly descending hilly road with intermittent speed humps and cars parked alongside the main right lane gave me a close up view of its slightly curving trajectory and braking behavior with regard to the humps. My thought on human or not was inconclusive until we reached a red light, and as I shot my eyes over and saw an empty driver seat, I smiled widely knowing that the software responds to brights flashed at 4-way stops (please don't tell me it doesn't and it just saw me indecisively not initiate at the stop).

You're right I don't have inside information, but we've been interacting with them on the street for years in SF. Waymos don't wait for human subjective guidance to give them clearance to pass, as evidenced by tons of videos and IRL experience. As soon as they come to a required stop, and if a vehicle or other object's linear travel path does not intersect it, it will go. Flashing lights will not change this behavior. (Yes you're right there is a regulatory requirement to respond to safety officer guidance, but compliance is spotty as evidenced by a lot of videos of vehicles entering active crime zones, etc.)

Waymo immitates humans insofar as its neural net trained on avoiding collisions after millions of miles of video footage and LIDAR data on roads shared with humans causes it to immitate humans.

It's likely manually programmed not to (incorrectly) turn the wheel to the left while stopped and waiting for an opportunity to turn. If you get rear-ended, you'll end up in the lane of oncoming traffic. It's certainly programmed to use its turn signals to indicate when it is going to turn. But after driving around thousands of cars without turn signals on but with their wheels pointed left, it "knows" to predict that they're about to turn, and might immitate humans by anticipating that action and moving to pass the stopped car on the right.

I have been hit 5-10x riding in NYC and SF (nothing serious, gratefully, mostly just people turning right not knowing/caring I was there), and the Waymo's awareness that I exist is immediately obvious and so different from a large percentage of human drivers. I hope the meaningful improvement in safety continues to convince people this should be a part of the future.

13X is way more impressive than it seems at first glance.

Let's take a simplistic model of accidents: that the average driver is at fault in an accident 50% of the time. So a perfect driver would only halve the number of accidents -- they only eliminate the accidents where they would otherwise have been at fault.

But Waymo's numbers are better than the "perfect" driver above. How is that possible? Because in most accidents the blame is not split 0%/100%. You can avoid a lot of accidents with defensive and safe driving.

13x compared to what ? The average driver is such a bullshit statistic - accidents are highly correlated with stuff like alcohol/drugs/lack of sleep/lack of experience/physical issues, then the other huge behavioral factor distraction and driving style, and on top of that car performance matters a lot too. I don't see any attempt to correct for that in their "human benchmark". Heck the least they could have done is compare to human taxi drivers which would be apples to apples. If it's 13x compared to that I'm sold for using it as a taxi service !

But individual driving - you can eliminate all those factors assuming you're a healthy, expericed driver with a new car. Nothing against self driving in principle but the failure cases I've seen look so bizarre - I'm way more comfortable with my limitations.

I did find the Waymos in SF disconcerting as they approached pedestrian crossings while I was waiting - with a human driver there's many different cues that they've seen you and noticed you - whether it be looking directly at you, or slowing down in preparation for you to cross.

I'm sure if I had just started walking across the crossing it would have reacted perfectly, but I wasn't willing - based on the lack of observable "I have noticed you" cues - to test that theory.

In Italy several cities lowered the maximum speed from 50 to 30 km/h.

There was a huge fight over it, car drivers in those cities were mad. Plenty of politicians opposed it.

Autonomous vehicles following proper signalling before lane changes can be safe at arbitrary speeds (see Autobahns working at all). Humans, we should limit passing speed to roughly ~5 mph delta between adjacent lanes and leave it at that.

Humans with adequate following distance in the entire lane can probably manage 10 mph delta. I routinely travel dozens of miles very safely at ~80 with the flow of traffic (including the cops), and been stressed out at 55 in the carpool lane through stop and go traffic in the right-hand lanes due to on ramps/offramps.

Because American drivers have normalized always driving 10 mph (16 km/h) over the speed limit.

Cops won't pull you over or write tickets if you're not at least 15 mph over, we basically don't have speed cameras, everyone's trying to win the rat race and dehumanizing other cars around them, and it's not considered morally wrong (by most) to break that specific part of the law.

So a single vehicle obeying the law will quickly get a long line of tailgaters and tailgaters of tailgaters trying to "push" the vehicle to go faster.

They can suck it, I'm not late or in a hurry, and my ancient truck, steel bumper, and class 5 receiver hitch will not be badly harmed by your plastic grille.

On most US highways (i.e. multi-lane limited access roads), it's customary to leave a path in the left 'passing lane' for any traffic that wants/needs to go faster than you. If cars match speeds across lanes, it impedes faster traffic.

The speed limit itself is a separate convention and regulation. In some places you can be cited for obstructing traffic by going the speed limit in the passing lane if you are matching the speed of cars to your right, effectively blocking the road.

We have a lot of freeway speed limits that are holdovers from the last oil crisis decades ago. Cars have gotten quieter, smoother, more capable, to the point where 55 mph is kind of hilariously slow.

That's just kind of tolerated in some places where the cops don't want to make waves with the wealthy older community.

A self-driving car never gets tired and sleepy after driving for many hours straight. A highway-bound Waymo would be safer than a few instances of distant past me who stayed on the road longer than I was safe to. They also never get drunk, and are safer than approximately 100% of impaired drivers.

Americans will vehemently deny this, but you're absolutely right.

It leads to other absurdities, like US cities frequently having parking minimums for bars. That's insane!

There's also the classic problem of people wildly misinterpreting statements and getting mad about it. You can say "we should design cities not centred around cars" and people will hear "I'm going to make it illegal for you to own a car".

> are reasonably happy with the status quo.

They're not, except for the having a car part. Road maintenance, especially in the suburbs, is hideously expensive and is falling further and further behind. Cars are the least efficient mode of transit, so traffic gets worse and worse. "Just one more lane" always makes it worse (induced demand), but that's the only solution being tried. The only way to make traffic better is to get significant numbers of people to switch to other modes, and you're simply not going to do that with "incremental improvements" because the status quo is so abysmal for anything other than a car. Cars themselves are horribly expensive and yet are required in most US cities; most are in effect paying a tax to car companies to participate in society.

That could just be, and seems to be in some cases at least, because Waymo doesn't behave like a human would, and people gets tripped up.

I don't doubt Waymos are very safe, but I always irk at these comparisons. Majority of human accidents are due to gross negligence and/or driving under some influence or serious fatigue. A system incapable of alcohol etc. is better than that? Well that is a substantially lower bar than you can possibly imagine. Add to that that all systems have constraints on how and where they are able to go. Combined even Tesla can be made to look good.

Depending on the context and question it might still be the question to pose. But people often make the leap to assume that a typical Waymo is x better than a typical human driver which is an entirely different question entirely.

Driving conventions vary wildly across states and even within them. And foreign drivers are a thing. A human who gets tripped up by a Waymo acting unusually will also get confused by someone getting used to no turns on right in Manhattan, driving on the right side of the road if coming in from the Commonwealth or adapting from California's protected left turners can turn into any lane, not just the leftmost. They'll also get confused by children and pets, who aren't bound by social custom, and deer, who aren't bound by physics.

But Waymos have driven so many miles by this point, if they are hiding some data that would tip the scales back towards human drivers I have yet to see it. If there is a way to slice the data that makes Waymo’s look less safe I would welcome the correction.

If Waymo truly has 80-90% fewer crashes in the conditions they drove in, then it still has policy implications for places like Phoenix that do have good conditions.

I've heard that Waymo relies on having very accurate map data for the areas where they operate, so perhaps they could perform worse than human drivers in areas where they don't have good map data.

But I also trust that the company wouldn't deploy them in those areas until the quality data they need is available. So perhaps "safer in the environments where they are actually deployed" would be more accurate, but that's also the only thing that matters.

Speculating about what would happen if they were used in ways they are neither intended to be used nor are actually used feels a little silly. Most machines can be unsafe if you use them in ways they're not intended to be used.

If you were choosing between getting into a Waymo or a car driven by a human driver (where Waymo operates, for a route that Waymo would do), the data shows that the Waymo is safer.

No, it does not. For one thing, we don’t have access to all the data, just what’s being told us. For another, it at best shows that Waymo is safer than average. Safer than an attentive London Cabby? I bet not.

In the US, we do have access to all the data [1]. They're required to report every incident with an injury or any amount of property damage, and it's all available for download as CSV.

No, it shows that Waymo is 6 to 12x safer than average.

I know that anecdotal experience is definitionally just that, anecdotal. But I've had a handful of attentive London cabby experiences (and enough in-Waymo experiences) that give me conviction that Waymos are far safer than them. They're out there driving all day every day, it's obvious to me that a Waymo driver is going to be safer than even a professional.

One cabby pulled out of a t junction to end up alongside me on a motorbike – a Waymo would never do that.

> By their own admission, this is not a straightforward comparison.

If they wanted to cherry pick, would they not omit that admission?

In any case, it seems plausible to me that the routes that Waymo drives are above average in human incidents, given that Waymo is probably overrepresented in high stress/traffic, inner city scenarios.

The comparison gets picked up as the headline; the admission does not. This is exploited quite often, e.g. in science reporting. I'm not saying this is what Waymo did - they don't seem to be bad actors - but absolutely, the pattern does occur.

I appreciate the skepticism. While I suspect motor vehicles that cannot be distracted would be safer than motor vehicles that can be, it shouldn't be claimed without real evidence.

If I were Google, I'd partner with some insurance carriers to compare the number of claim events normalized to the number of drivers on the road (approximated with Android data) in a city (same time of year, etc) before and after introducing Waymo. If claims per driver decreases, then I would be more inclined to support the claim that they're actually safer and that they don't just "seem safer"

Perhaps the comparison should only be to other taxis. Since I cannot buy a Waymo, it is not really relevant whether it is better than an average driver (including all the drunk ones, and the speed racers, etc).

There are other safety differences with human-driven vehicles… interpersonal violence does happen with taxis (e.g. drivers sexually harassing/assaulting passengers, passengers robbing drivers) - by definition those things cannot happen with a Waymo

accidents are not equally distributed across humans. more serious accidents will be caused by people who are habitually doing things that are unsafe but, for various reasons, most places lack effective ways to stop these people driving so they keep causing accidents.

the metric is not some nebulous aspect of skill but the bottom decile of human drivers causing accidents. it is not difficult to believe that an AI can drive better than this group, it is not a high bar, below the 10th percentile are people who should not be driving but cause most of the accidents.

Worth reviewing the methodology, rather than making stuff up.

I just watched a short that said some (all) Waymo drivers are not autonomous, but remote controlled by humans in the Phillipines.

I'm sure it's a combination of both since the latency would mean immediate reactions are impossible, but the presenter raised an interesting point, and that was that the remote drivers are not licensed to drive in the states that Waymo operated in, which would make it illegal.

Waymo uses remote contractors to hint the Waymo driver when it can't figure out a path forward. They're not being remote piloted.

They are however, very cagy about how often this is necessary.

They don't necessarily even hint them. I think the car mainly asks them yes/no questions and they respond.

except for the overwhelming evidence from video we already have that waymos are reacting than a human in the driver’s seat would, much less someone 200ms away.
