XC60 (156) Emergency brake assistant did not intervene

Good day together, I own (much more owned) an XC60, year 2017 (156 – predecessor model) The car has every possible driving / safety assistant, including emergency brake driver. I am also very satisfied with the car. However, the following brings me to ponder Last week I had changed lanes on the highway (on the right lane) and had a shoulder view. Exactly at the moment the car stopped in front of me. Since I had seen this too late, unfortunately, I could not prevent the drive up any more. It was a lot going on on on the highway. Was also not fast. Had only about 70-80 kmh on it. When I saw the car, I had still braked, but (very roughly estimated) drove up with about 30-40 kmh. Of course the system can not prevent any speed or impact. But I am of the opinion that this collision could be prevented by the assistant. Finally Volvo is working on marketing videos and so much more Temoi, as I did the end of the song… I did not have an economic accident and had a total damage to it. Anyway, I had an idea of “becoming”.
