To me, the real layer-8 in a car model is that you probably shouldn't have built out society to depend on cars in the first place. Thats why we have the idea of the 15 minute city: places you can manage without private transport.
Applied to s/w this would be "do we really need to make this system, in the first place: How about if we decide not to"
Yes. This is a system problem. Why are cars allowed to be near pedestrians? Why were cities/streets designed to make it possible for cars to run over pedestrians?
Saying it was an inattentive driver misses the point that we can't expect fallible people to not make mistakes. We should be designing systems to minimize the damage from inattentive drivers and drunk pedestrians
I've struggled to take my teams (in the past: I don't do PM now) beyond "ship it" to "kill it": the C-suites don't like the idea of stopping doing things. They have a point, we maybe don't have community permission, but we should at least entertain the idea (in the not for profit sector)
People rei-ify things. "oh we need to do X we've always done X" when in fact, you could say "doing X is stupid"
