This is obviously a fundamental design "feature", not a bug. The reason? I'll guess that the radar is tracking many stationary objects coming towards you all the time (overhead gantries, road signs, stopped cars in other lanes), and to eliminate "noise", the software has to simply ignore ALL stationary objects, otherwise it would have to interpret what they are and if they are a threat. Place a disclaimer in the user guide to prevent litigation, and you have a system that provides some [limited] benefit.
Also, the radar's maximum range appears to be about 200 meters. Not sure the car could stop in that distance (it works up to 120 mph) if it detected a static object. Would you really let software activate a full blown retina detaching emergency stop on the GUESS by the software that that object was a potential threat and predict that you'd keep the steering wheel in a straight line for the next 4 seconds (i.e. plan to hit it intentionally)? Doubt any manufacturer would sanction software that would provide this function.
Other manufacturers only seem to provide an up to 30 mph City Safety system for the above reasons, I'm guessing.
Still a great system if you keep alert.
