So on my trip today, I measured cabin nose and it seems a lot better than our M3.

56-57db @ 75mph - concrete

One problem with cameras is that you can't widen your view by moving your head left or right. The camera will just have a fixed viewing angle. Of course could be improved by making the camera more of a wide-angle one.I'd love to see the side mirrors go away. Check out how awesome e-tron and honda E systems are in Europe.
It will be a good while until those will be approved here with the regulators seemingly being hell bent against progress.
