My car has AEB and it's great. I'll never drive another car without it. Why not take the energy out of the impact? Humans aren't perfect, and even less so as we age.
"Impact" as in an inevitable crash. I like it because it has unquestionably caused the avoidance of two cases where my car would have hit something. Once when I was merging onto a freeway and the car ahead of me basically brakechecked panic'd at the last second while I was briefly looking over my shoulder at the traffic I was merging into, and the other when a friend of mine borrowed my car and nearly hit a deer. Both cases the AEB kicked in, the car came to a very aggressive halt, and the crash was avoided. Yes, the AEB has kicked in at other times, but on the whole, it's been great and I appreciate having it. Probably other manufacturers have different implementations and different experiences. Mine is a Tesla.
Why do you think it's great?
