    The radar works better with metallic objects, I suppose. No AEB for living things or concrete barriers apparently.

    I can't tell if that car even has AP.

    If it doesn't have AP then it doesn't have AEB.

    Now even if it did have AEB I doubt it would have done anything. Keep in mind that most AEB systems don't activate for large animals. They're mostly optimized/used for detecting cars, pedestrians, cyclist, etc.

    The exception being Volvo with their large animal detection. From what I can gather Volvo is considered to be the industry leader in AEB, and they only recently added large animal detection.

    Thought it worked with moving objects, not stationary ones? So it would work with a car in front of you that was slowing quickly. But not a car/bear stopped in the road.

    There was some talk back with Musk talking about avoiding people in traffic with the radar, he said something along the line that it would maybe, just maybe, detect something the size of a moose or deer (or something, maybe someone has a link to the quote) but not humans.

    So if the car was fitted with AP, maybe there was a chance it would detect it. But depending on how fast he was going, it may still have been a significant impact.

    I think until the image processing is advanced enough to identify such dangers, this is the best we can expect.

    Obviously the Tesla didn't look big enough.

    A bear likely darted from the woods at the last second not standing on the shoulder and stepped out at the last second like a pedestrian.
    Areas bears cross there is likely a elevation change and vegetation cover just off the shoulder of the road too which would complicate things further.

    So the question would be why would you expect the car to react?

    Was the bear just standing in the road or did it run across into the car's path? The latter is how most deer collisions happen, and I suspect how this happened too. If that's the case, then the car had no opportunity to respond.

    My AP2 car slowed for a deer that jumped into the road 40 yards ahead of me. I had AP activated so as I felt it slow I got the brakes to protect against potential other deer. After carefully scanning I resumed after that deer ambled off the road.
