My father and I have an annual tradition where we find a country and go get stuck in. I typically end up as the navigator and manage Google maps (among others).

My father and I have an annual tradition where we find a country and go get stuck in. I typically end up as the navigator and manage Google maps (among others). Having a dedicated navigator is the only safe way to use Google maps outside routine conditions, in my opinion. It often recommends incredibly dangerous detours that aren't visible in the navigation UI because they're off-screen. The only information you get is "alternate route available 3 minutes faster" that you have to decline in 10 seconds or it will autoselect. If you're lucky enough to have a dedicated navigator, they'll still have to know to review the entire change every time and have pretty extensive knowledge of the area to know those conditions ahead of time.
