It seems to me like angling the mirror further outward could be done with mirrors (or cameras) installed inside the car. The advantage of the outside mirror is that you can see the side of the car.
So if you prefer to drive with BGE mirrors, wouldn't you be better off leaving the outer mirrors so you can see along your side, and a bit to the rear, and install auxiliary outward-angled mirrors on the dashboard inside the car?
I know in one of our cars that the B-column is absolutely huge, and even swiveling my head is not enough to check the left blind spot, because that B-column is fat enough to hide a car. I have to check an auxiliary convex mirror before changing lanes left. That's mounted on the wing mirror, but I would have preferred it to be on the dash, because it eats up a lot of space on the regular mirror, and is still rather small in its own right.
