Yeah this thread has really squicked me out. Of course dehumanization is an age-old tactic for enabling asshole behaviors of all sorts. I'd like to hope, however, that outside the current commuter-hell driving context, few people would even admit to themselves, let alone broadcast to the world, their considered preference for killing children. That is, when they no longer drive, perhaps people won't be quite so insan…
I don't even drive at all, and yet this thread irks me from the other direction. Dehumanization is an age-old tactic for enabling asshole behaviors, and bringing children into a discussion is an age old tactic for justifying irrational decisions ("Think of the children"). You claimed that any car may be driven slowly enough to avoid killing people on the road with only mere convenient to others. That's patently false…
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.
