the point i am trying to make is about 'vehicle integration' most of the oems don't make their own emotors. they 'engineer' vehicle attributes and provide the suppliers like Bosch with system level targets. this process is generally referred to as target cascading. if i want motor to sound xdB at driver ear, my vehicle needs to provide ydB isolation and then source needs to be at zdB, if this process is not hashed out well, you end up with poor isolation. you also have to consider variability in source and your manufacturing. This is the area where an automaker shines or crumbles, doing this poorly results in poor experience and hence poor reliability/quality. most of major oems think rivian is struggling in this area and just now laid of most of the sme's lol
