Really depends on where you are in Europe. Out here in the boonies of Portugal, it’s excellent if you’re driving a 4x4 pickup truck, which is the only vehicle of mine I use it with, as it picks very direct routes, which often involve ridiculously steep muddy dirt tracks, very narrow bridges, and generally just very underused farm tracks.

I tried using it in Bosnia, once, and it decided to use an abandoned airfield landing strip as a shortcut. Wild stuff.
