I had almost the exact same accident last fall. I feel your pain.
AP1 didn't see the posts either. I was changing lanes (at night) and didn't see them up ahead. Did the auto-lane change on AP1 and was looking up at the overhead road side describing which lane was HOV vs express and which wasn't and the delineator posts appeared mid lane change. I drove by the same area later and took a video. You'll see 3 posts knocked down in the screenshot attached and the damage they did. Never had a collision warning or any alerts from the car whatsoever. It just plowed through the posts and continued on it's lane change. I torqued the wheel immediately and disengaged autosteer but it was too late.
Ended up having to replace the hood, front bumper and the headlight cover.
