That sucks, and I love to hate on "self driving" cars. But it wasn't speeding to start with (assuming speed limit in the school zone was 20 or 25), braked as much as possible, and the company took over all the things a human driver would have been expected to do in the same situation. Could have been a lot worse, probably wouldn't have been any better with a human driver (just going to ignore as no-signal Waymo's models that say an attentive human driver would have been worse). It's "fine". In this situation, cars period are the problem, not "self driving" cars.

If waymo is to be believed, they hit the kid at 6mph and estimated that a human driver at full attention would have hit the kid at 14 mph. The waymo was traveling 17mph. The situation of "kid running out between cars" will likley never be solved either, because even with sub nanosecond reaction time, the car's mass and tire's traction physically caps how fast a change in velocity can happen. I don't think we will eve…
That doesn't mean it can't be solved. Don't drive faster than you can see. If you're driving 6 feet from a parked car, you can go slow enough to stop assuming a worst case of a sprinter waiting to leap out at every moment.
If we adopted that level of risk, we'd have 5mph speed limits on every street with parking. As a society, we've decided that's overly cautious.

#113A human driver would most likely have killed this child. That's what should be on the ledger.
That's pretty hyperbolic. At less than 20 mph, car vs pedestrial is unlikely to result in death. IIHS says [1] in an article about other things:
> As far as fatalities were concerned, pedestrians struck at 20 mph had only a 1% chance of dying from their injuries
Certainly, being struck at 6 mph rather than 17 mph is likely to result in a much better outcome for the pedestrian. And that should not be minimized; although it is valuable to consider the situation (when we have sufficient information) and validate Waymo's suggestion that the average human driver would also have struck the pedestrian and at greater speed. That may or may not be accurate, given the context of a busy school dropoff situation... many human drivers are extra cautious in that context and may not have reached that speed; depending on the end to end route, some human drivers would have avoided the street with the school all together based on the time, etc. It's certainly seems like a good result for the premise, child unexpectedly appears from between large parked vehicles, but maybe there should have been an expectation.

Yup.

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.)

For me, the policy question I want answered is if this was a human driver we would have a clear person to sue for liability and damages. For a computer, who is ultimately responsible in a situation where suing for compensation happens? Is it the company? An officer in the company? This creates a situation where a company can afford to bury litigants in costs to even sue, whereas a private driver would lean on their i…
Waymo hits you -> you seek relief from Waymo's insurance company. Waymo's insurance premium go up. Waymo can weather a LOT of that. Business is still good. Thus, poor financial feedback loop. No real skin in the game.
John Smith hits you -> you seek relief from John's insurance company. John's insurance premium goes up. He can't afford that. Thus, effective financial feedback loop. Real skin in the game.
NOW ... add criminal fault due to driving decision or state of vehicle ... John goes to jail. Waymo? Still making money in the large. I'd like to see more skin in their game.

Orders of magnitude? Something like 100 people die on the road in the US each day. If self-driving tech could save 10 lives per day, that’s wouldn’t be good enough?
"It depends". If 50 people die and 50 people go to jail, vs. 40 people die and their families are left wondering if someone will take responsibility? Then that's not immediately standing out as an improvement just because fewer died. We can do better I think. The problem is simply one of responsibility.
People don't usually go to jail. Unless the driver is drunk or there's some other level of provable criminal negligence (or someone actively trying to kill people by e.g. driving into a crowd of protesters they disagree with), it's just chalked up as an accident.

It depends on the situation, and we need more data/video. But if there are a bunch of children milling about an elementary school in a chaotic situation with lots of double parking, 17 mph is too fast, and the Waymo should have been driving more conservatively.

UK driving theory test has a part called Hazard Perception: not reacting on children milling around would be considered a fail.

John probably (at least where I live) does not have insurance, maybe I could sue him, but he has no assets to speak of (especially if he is living out of his car), so I'm just going to pay a bunch of legal fees for nothing. He doesn't car, because he has no skin in the game. The state doesn't care, they aren't going to throw him in jail or even take away his license (if he has one), they aren't going to even impound his car.
Honestly, I'd much rather be hit by a Waymo than John.

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.
