Sorry, coming in late, but gotta object here...

My Subaru has no problem detecting stationary objects. It uses stereo cameras, for which object detection and locating the object is a thoroughly solved problem, whether the object is moving or stationary. No magic needed. It just works. For example, there is a sharp turn near my home with prominent turn signs along the curve, which puts them directly in front of you as you approach the turn. Those stationary signs quite reliably set off my collision warning if I'm approaching them too fast.

Tesla has the problem because it uses radar for object detection. The radar can tell them the presence of an object, but cannot tell them the object's location. An overhead sign or overpass or whatever looks the same as an object in the road. So to avoid countless false positives, they need to ignore signals from stationary objects because they chose to use radar. It's a self-inflicted problem that other vehicles do not have.
