So I have no Tesla and no other vehicle that would have these features, and I'm confused. I thought Tesla already had collision avoidance released when TACC was released. Now, today, it is announced that Automatic Emergency Braking is coming to a Tesla near you. I don't know the difference. From the descriptions I read, they do the same thing. Did I just misunderstand collision avoidance? I read about people not being brave enough to see if the car would stop for a stopped vehicle in front of them, so they obviously expected that to be an existing feature. Maybe collision avoidance is a TACC-controlled feature, and automatic emergency braking works under normal driver-controlled conditions? Somebody educate me, please!
