yellow line on road seems to perfectly align with the yellow barrier. camera didn't identify the wall. I don't think they have radar to identify solid objects, do they? Isn't it just camera? I can't remember right now and too lazy to look it up.

I don't know what system they're using, but they really need to get a handle on it. For as many accidents as they avoid, not hitting stopped objects is pretty important from a safety perspective.
