You never know when someone might need to do a full, 100% brake slam to avoid something.
I don't know about you, but I usually look beyond the car in front and possibly the one in front of that one too in order to anticipate braking. If it's all clear ahead and the one immediately in front suddenly brakes hard, I don't think it's clear that it isn't culpable.
