In reply to the "what about the expert" comments, bear in mind that the alert is when the route deviates by over 500m.
So in urban areas this isn't going to trigger for most cases where it's just a smarter neighbouring road, it'll be where there's a significant deviation.
And this doesn't have to result in arguments: just politely asking the driver about the route seems a fair start
