I believe you, that you don't drive at all. You call both situations strawmen, yet each is a common occurrence. Safe speed in an automobile is proportional to sightline distance. If drivers or robocars see a child (or any hazard) near the road, they should slow down. By the time they reach the child, they should be crawling. That's in an urban alley or on a rural interstate. If the child appeared before the driver or robocar could react, the car was traveling too fast for that particular situation.

In that "traveling too fast" failure mode, previous considerations of convenience or property damage no longer apply. The driver or robocar already fucked up, and no longer has standing to weigh any value over the safety of pedestrians. Yes it's sad that the three kids in the backseat will be woken from their naps, but their complaint is with the driver or robocar for the unsafe speeds, not with the pedestrian for her sudden appearance.

This is the way driving has always worked, and it's no wonder. We're talking about kids who must be protected from the car, but we could be talking about hazards from which the car itself must be protected. If you're buzzing along at 75 mph and a dumptruck pulls out in front of you, you might have the right-of-way, but you're dead anyway. You shouldn't have been traveling that fast, in a situation in which a dumptruck could suddenly occupy your lane. In that failure mode, you're just dead; you don't get to choose to sacrifice some children to your continued existence.

Fortunately, the people who actually design robocars know all this, so the fucked-up hypothetical preferences of solipsists who shouldn't ever control an automobile don't apply.
