I think my problem is that it reacted after seeing the child step out from behind the SUV.
An excellent driver would have already seen that possible scenario and would have already slowed to 10 MPH or less to begin with.
(It's how I taught my daughter's to drive "defensively"—look for "red flags" and be prepared for the worst-case scenario. SUV near a school and I cannot see behind it? Red flag—slow the fuck down.)
First, it's still the automobile's fault.
At least it was already slowed down to 17 mph to start. Remember that viral video of some Australian in a pickup ragdolling a girl across the road? Most every comment is "well he was going the speed limit no fault for him!" No asshole, you hit someone. It's your fault. He got zero charges and the girl was seriously injured.
You seem to be implying that there are no circumstances in which a vehicle can hit a pedestrian and the driver not be at fault... which is absurd.
Just about absolute. Fall off bridge onto car, I guess not. Olympic sprinter dashes out from car intentionally trying to be hit? Guess not either. Clothed mostly in black on a rainy night on a freeway? Not either.
But you hit a kid in daytime? It's your fault. Period.

It is absurd, but that doesn't mean that the attitude can't be useful!
In teaching my teenager to drive, I drilled into him the fact that, in every accident, regardless of who is "at fault", there is almost always something that the other party could have done to mitigate it. I gave him plenty of situations as examples...
You're going down a street that has kids on the sidewalk? You better be prepared to have one of those kids come out in front of the car while rough-housing, playing, whatever.
You had right of way? Maybe you did, but did you even look at the opposing traffic to see if it was safe to proceed or did you just look at the traffic light?
I've driven, thus far in my life, roughly 600000km (maybe more) with 2x non-trivial accidents, both ruled not my fault. In hindsight, I could have avoided both of them (I was young and not so self-aware).
I'm paranoid when driving, and my stats are much much better than Waymo's (have never injured anyone - even my 2x accidents only had me injured), even though I drive in all sorts of conditions, and on all sorts of roads (many rural, some without markings).
Most people don't drive like this though (although their accident rate is still better than Waymo's).
No it's not. The same principle applies to rules of right of way on the water. Technically the 32 foot sailboat has right of way over a triple-E because the triple-E uses mechanical propulsion.
You have a responsibility to be cautious in heavy equipment no matter what the signage on the road says, and that includes keeping a speed at which you can stop safely if a person suddenly steps onto the road in situations where people are around. If you are driving past a busy bar in downtown, a drunk person might step out and you have a responsibility to assume that might happen. If you have to go slower sometimes, tough.

You mean the Aussie one where the guy was going an appropriate speed for the area and when the cops arrived the parents and their neighbors LIED TO THE POLICE and said he was hooning down the road at excess speed and hit the kid? And that he was only saved from prison by having a dash cam that proved the lies to be lies? That one?
That logic is utter bs, if someone jumps out when you're travelling at an appropriate speed and you do your best to stop then that's all that can be done. Otherwise by your logic the only safe speed is 0.

That’s not how fault works
It's not the drivers fault when they hit a kid who darts out in front of them and they had no time to react and weren't doing anything illegal like speeding.
They could have driven with more care and attention if they're passing large vehicles that block their view of any children.
I don't see how that's feasible without introducing a lot of friction.
Near my house, almost the entire trip from the freeway to my house is via a single lane with parked cars on the side. I would have to drive 10 MPH the entire way (speed limit is 25, so 2.5x as long).
Why can't we add friction to save lives? Automobiles are the single leading cause of death for children in the USA! We're not talking about something uncommon.
Remove the free parking if that's making the road unsafe. Or drive 10 mph. Done.
But you most likely don't have that entire road be full of little kids in the sidewalk all the way. If you did, then yes probably 10mph or less would be wise.
Yes.
- Parked cars on the street. - Drive somewhat fast. - Avoid killing people.
Pick two.
It's hard to consider it "lots of friction" in a vehicle where you press a button to go faster and another button to slow down.
A single lane residential street with zero visibility seems like an obvious time to slow down. And that's what the Waymo did.
That's why the speed limit is 25 (lower when children are present in some areas) and not 35 or 40 etc. It's not reasonable to expect people to drive at 40% of the posted speed limit the entire way. We're also not talking about zero visibility (e.g. heavy fog). We're talking about blind spots behind parked cars, which in dense areas of a city is a large part of the city. If we think as a society in those situations the safe speed is 10 mph, then the speed limit should be 10mph.

I mean, you are putting your finger right on the answer: the whole car thing doesn't work or make sense, and trying to make autonomous vehicles solve the unsolvable is never going to succeed.
Agreed.
Car culture in the US is toxic, and a lot of accidents and fatalities are a result of how poorly designed our infrastructure is. We design for cars, not for people (just one more lane bro, will totally fix traffic. Nevermind that a train can move double the capacity of that entire line of traffic).
Cars are the wrong solution, particularly in urban areas. A self driving car is still a car, and comes along with all the same problems that cars cause.
Aye, and to always look for feet under and by the front wheel of vehicles like that.
Stopped buses similarly, people get off the bus, whip around the front of them and straight into the streets, so many times I’ve spotted someone’s feet under the front before they come around and into the street.
Not to take away from Waymo here, agree with thread sentiment that they seem to have acted exemplary
You can spot someone's feet under the width of a bus when they're on the opposite side of the bus and you're sitting in a vehicle at a much higher position on the opposite side that the bus is on? That's physically impossible.
In normal (traditional?) European city cars, yes, I look for feet or shadows or other signs that there is a person in the other side. In SUVs this is largely impossible but then sometimes you can see heads or backpacks.
Or you look for reflections in the cars parked around it. This is what I was taught as “defensive“ driving.
I think you're missing something though, which I've observed from reading these comments - HN commenters aren't ordinary humans, they're super-humans with cosmic powers of awareness, visibility, reactions and judgement.

>reacted after seeing the child step out from behind the SUV.
Lmao most drivers I see on the roads aren't even capable of slowing down for a pedestrian crossing when the view of the second half of the crossing is blocked by traffic (ie they cannot see if someone is about to step out, especially a child).
Humans are utterly terrible drivers.
They don't even stop when it's a crosswalk with a flashing light system installed and there are no obstructions.
>> Humans are utterly terrible drivers
Duh, driver is, essentially, a type of specialized profession. It's kinda unreasonable to think that everyone could learn to do it well
Good thing we have public transport! :D
Yes and no. Tons of situations where this is simply not possible, whole traffic goes full allowed speed next to row of parked cars. If somebody unexpectedly pops up distracted, its a tragedy guaranteed regardless of driver's skills and experience.
In low traffic of course it can be different. But its unrealistic to expect anybody to drive in expectation that behind every single car passed there may be a child jumping right in front of the car. That can be easily thousands of cars, every day, whole life. Impossible.
We don't read about 99.9% of the cases where even semi decent driver can handle it safely, but rare cases make the news.
I slow down considerably near parked cars. And I try to slow down much earlier approaching intersections where there are parked cars blocking my view of cross walk entries. I need to be able to come to full stop earlier than intersection if there happens to be a pedestrian there.
I kind of drive that way. I slow down, move as far away in my lane from the parked cars as possible. It's certainly what I would expect from a machine that would claim to be as good as the best human driver.
> a machine that would claim to be as good as the best human driver.
Does Waymo claim that? If so I haven't seen it. That should of course be the goal, but "better than the average human driver" should be the bar.

This is generally the problem with self-driving cars, at least in my experience (Tesla FSD).
They don't look far enough ahead to anticipate what might happen and already put themselves in a position to prepare for that possibility. I'm not sure they benefit from accumulated knowledge? (Maybe Waymo does, that's an interesting question.) I.e., I know that my son's elementary school is around the corner so as I turn I'm already anticipating the school zone (that starts a block away) rather than only detecting it once I've made the turn.
Tesla FSD is leagues behind Waymo; generalizing based on your Tesla experience doesn't make sense.
Evidence of this? I own a Tesla (HW4, latest FSD) as well as have taken many Waymo rides, and have found both to react well to unpredictable situations (i.e. a car unexpectedly turning in front of you), far more quickly than I would expect most human drivers to react.
This certainly may have been true of older Teslas with HW3 and older FSD builds (I had one, and yes you couldn't trust it).
So... the thing is it's really not. They're behind on schedule, having just launched in public. But FSD has been showing capabilities in regular use (highway navigation, unprotected left turns in traffic, non-geofenced operation areas based solely on road markings) that Waymo hasn't even tried to deploy yet.
It's much more of a competition than I suspect a lot of people realize.
Intellectually this doesn't even compute. Waymo is tele-oped in like 5 cities and FSD works in 5 countries. It's not even close.
Yes I agree, but why 10mph? Why not 5mph? or 2mph? You'll still hit them if they step out right in front of you and you don't have time to react.
Obviously the distances are different at that speed, but if the person steps out so close that you cannot react in time, you're fucked at any speed.
10mph will do serious damage still, so please for the sake of the children please slow yourself and your daughter's driving down to 0.5mph where there are pedestrians or parked cars.
But seriously I think you'd be more safe to both slow down and also to put more space between the parked cars and your car so that you are not scooting along with a 30cm of clearance - move out and leave lots of space so there is more space for sight-lines for both you and pedestrians.
