> the pedestrian suddenly entered the roadway from behind a tall SUV, moving directly into our vehicle's path. Our technology immediately detected the individual as soon as they began to emerge from behind the stopped vehicle. The Waymo Driver braked hard, reducing speed from approximately 17 mph to under 6 mph before contact was made.

I honestly cannot imagine a better outcome or handling of the situation.
> Waymo said in its blog post that its “peer-reviewed model” shows a “fully attentive human driver in this same situation would have made contact with the pedestrian at approximately 14 mph.”
It's likely that a fully-attentive human driver would have done worse. With a distracted driver (a huge portion of human drivers) it could've been catastrophic.
These giant SUVs really are the worst when it comes to child safety
The question will be whether 17 mph was a reasonably cautious speed for this specific scenario. Many school zones have 15 mph limits and when there are kids about people may go even slower. At the same time, the general rule in CA for school zone is 25 mph. Clearly the car had some level of caution which is good.
What I would like to see is a full-scale vehicle simulator where humans are tested against virtual scenarios that faithfully recreate autonomous driving accidents to see how "most people" would have acted in the minutes leading up to the event as well as the accident itself
This is the fault of the software and company implementing it.
Having performed this exact test on 3 dozen vehicles (L2/L3/L4) for several AV companies in the Bay Area [1], I would say that Waymo's response, per their blog post [2] has been textbook compliance. (I'm not defending their performance... just their response to the collision). This test / protocol is hard for any driver (including human driven vehicles), let alone ADAS/L3/L4 vehicles, for various reasons, including: pedestrian occlusion, late ped detection, late braking, slick roads, not enough braking, etc. etc.
Having said all that, full collision avoidance would have been best outcome, which, in this case, it wasn't. Wherever the legal fault may lie -- and there will be big debate here -- Waymo will still have to accept some responsibility, given how aggressively they are rolling out their commercial services.
This only puts more onus on their team to demonstrate a far higher standard of driving than human drivers. Sorry, that's just the way societal acceptance is. We expect more from our robots than from our fellow humans.

(edit: verbiage)
I think the overall picture is a pretty fantastic outcome -- even a single event is a newsworthy moment _because it's so rare_ .
> The NHTSA’s Office of Defects Investigation is investigating “whether the Waymo AV exercised appropriate caution given, among other things, its proximity to the elementary school during drop off hours, and the presence of young pedestrians and other potential vulnerable road users.”
Meanwhile in my area of the world parents are busy, stressed, and on their phones, and pressing the accelerator hard because they're time pressured and feel like that will make up for the 5 minutes late they are on a 15 minute drive... The truth is this technology is, as far as i can tell, superior to humans in a high number of situations if only for a lack of emotionality (and inability to text and drive / drink and drive)... but for some reason the world wants to keep nit picking it.
A story, my grandpa drove for longer than he should have. Yes him losing his license would have been the optimal case. But, pragmatically that didn't happen... him being in and using a Waymo (or Cruise, RIP) car would have been a marginal improvement on the situation.
Surprised at how many comments here seem eager to praise Waymo based off their PR statement. Sure it sounds great if you read that the Waymo slowed down faster than a human. But would a human truly have hit the child here? Two blocks from a school with tons of kids, crossing guards, double parked cars, etc? The same Waymo that is under investigation for passing school busses illegally? It may have been entirely avoidable for the average human in this situation, but the robotaxi had a blind spot that it couldn't reason around and drove negligently.
Maybe the robotaxi did prevent some harm by braking with superhuman speed. But I am personally unconvinced it was a completely unavoidable freak accident type of situation without seeing more evidence than a blog post by a company with a heavily vested interest in the situation. I have anecdotally seen Waymo in my area drive poorly in various situations, and I'm sure I'm not the only one.
There's the classic "humans are bad drivers" but I don't think that is an excuse to not look critically into robotaxi accidents. A human driver who hit a child next to a school would have a personal responsibility and might face real jail time or at the least be put on trial and investigated. Who at Waymo will face similar consequences or risk for the same outcome?
While it's third-hand, word on the local parent chat is that the parent dropped their kid off on the opposite side of the street from Grant. Even though there was a crossing guard, the kid ran behind a car an ran right out in to the street.
If those rumors are correct, I'll say the kid's/family's fault. That said, I think autonomous vehicles should probably go extra-slowly near schools, especially during pickup and dropoff.
And it is not the child’s or their parents’ fault either:
Once you accept elementary school aged children exist, you have to accept they will sometimes run out like this. Children just don’t have the same impulse control as adults. And honestly even for adults stepping out a bit from behind an obstacle in the path of a car is an easy mistake to make. Don’t forget that for children an SUV is well above head height so it isn’t even possible for them to totally avoid stepping out a bit before looking. (And I don’t think stepping out vs. running out changes the outcome a lot)
This is why low speed limits around schools exist.
So I would say the Waymo did pretty well here, it travelled at a speed where it was still able to avoid not only a fatality but also major injury.

Yes, kids in developed countries have the autonomy to go to school by themselves from a very young age, provided the correct mindset and a safe environment. That's a combination of:
* high-trust society: commuting alone or in a small group is the norm, soccer moms a rare exception,
* safe, separated lanes for biking/walking when that's an option.
This will continue to be the debate—whether human performance would have exceeded that of the autonomous system.
Bad any other car been there, probably including Tesla, the poor kid would have been hit with 4-10x more force.
US human drivers average ~3.3 trillion miles per year [1]. US human drivers cause ~7,000 child pedestrian injurys per year [2]. That amounts to a average of 1 child pedestrian injury per ~470 million miles. Waymo has done ~100-200 million fully autonomous miles [3][4]. That means they average 1 child pedestrian injury per ~100-200 million miles. That is a injury rate ~2-4x higher than the human average.
However, the child pedestrian injury rate is only a official estimate (possible undercounting relative to highly scrutinized Waymo miles) and is a whole US average (operational domain might not be comparable, though this could easily swing either way), but absent more precise and better information, we should default to the calculated 2-4x higher injury rate; it is up to Waymo to robustly demonstrate otherwise.
Furthermore, Waymo has published reasonably robust claims arguing they achieve ~90% crash reduction [5] in total. The most likely new hypotheses in light of this crash are:
A. Their systems are not actually robustly 10x better than human drivers. Waymos claims are incorrect or non-comparable.
B. There are child-specific risk factors that humans account for that Waymo does not that cause a 20-40x differential risk around children relative to normal Waymo driving.
C. This is a fluke child pedestrian injury. Time will tell. Given their relatively robustly claimed 90% crash reduction, it is likely prudent to allow further operation in general, though possibly not in certain contexts.

Waymo hits a kid? Ban the tech immediately, obviously it needs more work.
Waymo hits a kid? Well if it was a human driver the kid might well have been dead rather than bruised.

BUT! As a human driver, I avoid driving near the schools when school's letting out. There's a high school on my way home and kids saunter and jaywalk across the street, and they're all 'too cool' to press the button that turns on the blinking crosswalk. So I go a block out of my way to bypass the whole school area when I'm heading home that way.
Waymos should use the same rationale. If you can avoid going past a school zone when kids are likely to be there, do it!
The issue is that I don’t trust a private company word. You can’t even trust the president of the USA government nowadays… release the video footage or get lost.
The argument that questions "would a human be driving 17mph in a school zone" feels absurd to the point of being potentially disingenuous. I've walked and driven through many school zones before, and human drivers routinely drive above 17mph (in some cases, over the typical 20mph or 25mph legal limit). It feels like in deconstructing some of these incidences, critics imagine a hypothetical scenario in which they are driving a car and its their only job to avoid a specific accident that they know will happen in advance, rather than facing the reality of what human drivers are actually like on the road.
But in a human driver with FSD on, are they liable if FSD fails? My understanding is yes, they are. Tesla doesn't want that liability. And to me this helps explain why FSD adoption is difficult. I don't want to hand control over to a probabilistic system that might fail but I would be at fault. In other words, I trust my own driving more than the FSD (I could be right or wrong, but I think most people will feel the same way).
If Waymo has fewer accidents where a pedestrian is hit than humans do, Waymo is safer. Period.
A lot of people are conjecturing how safe a human is in certain complicated scenarios (pedestrian emerging from behind a bus, driver holds cup of coffee, the sun is in their eyes, blah blah blah). These scenarios are distractions from the actual facts.
Is Waymo statistically safer? (spoiler: yes)
Our car hits better is a win, I guess?
Glad the child is okay.
Great job, Waymo, for maybe hitting a little kid less than your study assumes a human would have! Is that study legit? Who cares, we trust you!
If this had been Tesla, HN would have crashed from all the dunking.
As this is based on detection of the child, what happens on Halloween when kids are all over the place and do not necessarily look like kids?
