I find that 95% of the time the traffic is too far away to be seen unless you have labels on, which I don’t because they look wrong. Even max zoom on the view through the windows, I hardly ever manage to see the traffic, even looking up and down.
I’ve no idea how far away these things are, would be nice to only be informed if it’s reasonably close range at a similar altitude, but it doesn’t seem to work like that.
