It's not necessarily about "advantage", especially on longer journeys. What if there is a crash on the Autobahn 1 hour in front of me? Even if I don't reroute, I at least have a choice of planning my toilet and lunch stop _before_ the crash site.

It is also possible to plan a different route if the crash is visible so far ahead. There are usually multiple routes I could take, and I decide based on the traffic and other factors, where I go. It can depend on the time of day, the time of year, etc. Maybe usually I don't take the one which is 100kms longer, but in the case of a crash, or even just heavy traffic it could be quicker still.

So for any non-trivial journey, I always use navigation, even if I could drive to the other place blindly. It's not really about navigation, it is about the current situation on the roads.
