the only visibility problem i have with my calais (same car as G8/SS) is the front A pillor is too thick, it blocks my vision when turning and have to move back or forward to look around it, common problem on modern cars with a high saftey rating,
as for side and rear view, vision is good, as ameriacan-muscle said it's more about lazy drivers, don't know the sound yet but their is an icon in the door mirror which lights up when activated, you move over into somebodys lane the alarm goes off
it is also a good way to motivate a sleepy driver into paying attention
