a yellow light or a car in front is very well predictable, if you feel you should be slowing down and the car isn't, you have time for apply correction, car not slowing down is an implicit warning of autopilot malfunction you can act upon. a emergency vehicle blocking a tiny fraction of the lane doesn't require as much slowing, you can just slightly move left of your lane to compensate. car not slowing down doesn't trigger the same "brain" warning, because you don't expect it to. this is what sets these crashes aside from the other, you get no explicit and no implicit warning
