A field to set the maximum angle for button look.
That way we can constrain it to say 15 degrees left-right and be able to look at the mirrors of the BF1 with a 75 degree FOV setting. It's also useful for checking the side mirrors of the road cars. If it is saved differently per-car (as the custom camera settings are) so much the better.

+1

But afaik the side mirrors show exactly the same picture as the rear mirror.

Mentioned many times before.. Also different angle for left and right, coz you need larger angle for right side in tintops (if you sit on the left)

Oops - right you are, a better search in the forum yielded this:

Sorry for mentioning the same thing.

+1, whether it's been mentioned before or not. My neck doesn't move to that angle when i'm racing - especially not since the accident...
