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?
17 mph is way too fast near a school if it's around the time children are getting out (or in).
"and thereby hitting the child ... is a success."

no, i expect them to slow down when children may be present
This isn't Apollo 13 with a successful failure. A driverless car hit a human that just happened to be a kid. Doesn't matter if a human would have as well, the super safe driverless car hit a kid. Nothing else matters. Driverless car failed.
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.
