The BSW worked however the engineering of this particular BSW on this model is such that I feel it did not provide the queues in such a manner as to gain immediate visual/audible attention. The BSW is positioned inside the vehicle to the left and right near the sideview mirrors but obscured enough in one's vision that it does not gain ready attention. The audible portion is not adjustable in volume and when on a busy interstate with navigation guiding you it is very difficult to hear. I was in blind spot collision accident on 10/4/2021 in VA on 395S at 3:30pm EST. I looked, looked again and did not see the vehicle in my blind spot and I genuinely feel that the BSW in this vehicle is not sufficient to alert a driver in those conditions in a manner that garners the drivers immediate attention. Having been placed in rental vehicle that has the BSW warning embedded in the sideview mirror itself I find that to be a much more immediate attention grabber than Nissan's BSW construct in my vehicle such that I have purchased aftermarket BSW mirrors to place on my sideview mirrors to prevent /assist with this issue.
