Immediately hitting the brakes when a child suddenly appears in front of you, instead of waiting 500ms like a human, and thereby hitting the child at a speed of 6 instead of 14 is a success.
What else to you expect them to do, only run on grade–separated areas where children can't access? Blare sirens so children get scared away from roads? Shouldn't human–driven cars do the same thing then?

So by that logic, if we cured cancer but the treatment came with terrible side effects it wouldn't be considered a "success"? Does everything have to perfect to be a success?
The raw corporate goals? Safe enough to be allowed on roads.
The less cynical set of goals would be safer than the mean human, then safer than the median human, then safer every year indefinitely.
17 mph is way too fast near a school if it's around the time children are getting out (or in).
The limit is 20 MPH in Washington state, in California the default is 25 MPH, but is going to 20 MPH soon and can be further lowered to 15 MPH with special considerations.
The real killer here is the crazy American on street parking, which limits visibility of both pedestrians and oncoming vehicles. Every school should be a no street parking zone. But parents are going to whine they can't load and unload their kids close to the school.
On street parking is so ingrained into the American lifestyle that any change to the status quo is impossible. Cars have more rights on public property than people. Every suburban neighborhood has conflicts over people's imagined "ownership" of the street parking in front of their house. People rarely use their garages to store their car since they can just leave it on the street. There are often laws that prevent people from other neighborhoods from using the public street to park. New roads are paved as wide as possible to allow both street parking and a double-parked car to not impede traffic. And we've started building homes without any kind of parking that force people to use the street.

Plenty of American cities regulate or even eliminated, in various measures, on-street parking.
If it had no parking, then the parents would be parked somewhere else and loading and unloading their kids there, and then that would need to be a no-parking zone too.
I guess you could keep doing that until kids just walk to and from school?
Our local school has them unload a block away unless they are handicapped. A kid isn't going to die walking a block. But its pointless because they still allow residential on street parking around the school, and my son has to use a crosswalk where cars routinely park so close to, I had to tell him that the traffic (pretty heavy) on the road wouldn't see him easily, and he should always ease his way into a crosswalk and not assume he would be easily seen.
In the UK we have a great big yellow zig-zag road marking that extends 2/3rds the width of an average car across the road. It means "this is a school, take your car and fuck off". You find it around school gates, to a distance of a few car lengths either side of the gate, and sometimes all along the road beside a school.
It doesn't stop all on street parking beside the school, but it cuts it down a noticeable amount.
Same for my tiny town. Stopping on the road is 100% not allowed, and parking isn't allowed there either. The school has its own parking area to park and pick up/drop off kids, and cars in there creep at 2 or 3 MPH.
"and thereby hitting the child ... is a success."

no, i expect them to slow down when children may be present
how about 10-15 mph if directly adjacent to a school, especially during the bands before and after school stars or ends. route away from schools whenever feasible.
A vehicle can't go 10 to 15 miles per hour at the same time. If it was going 15, then it should have been going 10. Or driving further away from occluded spaces. And again, routing away from schools.
The simple fact is that it hit a child and even though it wasn't a serious issue due to their safety policies, there's still room for improvement in these technologies.
And since it's a robot, and not a human, you can actually make changes and have them stick. For example, routing away from schools during certain hours.
If failure is defined such that failure is the only possible outcome, I don't think it's a useful part of an evaluation.
I don't know the implementation details, but success would be not hitting pedestrians. You have some interesting ideas on how to achieve that but there might be other ways, I don't know.
