Personally I find having navigation directions on my wrist very useful, especially when bicycling/walking
Much better to get a visual idea of the area, so you know where you are, distances to expect, and layout of the land... kind of like a normal map!
I get that looking at a map is not practical when cycling, but I think most cyclists know exactly where they and following familiar routes.
It's useful, when navigating, to be free of the need to stare at one's phone or a map the whole time. That's the boon here.
But, again, I note you're the guy who seems really invested in hating the watch -- even to the point of dismissing as invalid reasons another poster enjoys it! -- so it's not clear why I'm replying.
