I've always had trouble with navigation apps in Serbia. At one spot (way off the main highway), a nice fresh road just suddenly ended. We were just about 10 meters short of finishing the maneuver Google was suggesting.

I couldn't bring myself to follow that dumb robot's advice. So I had to find a detour the hard way.

(Turns out later, Google was expecting me to somehow figure out I should've turned onto some unremarkable alternate road a kilometer back, with no prompt to turn and no indication I'd gone the wrong way, even though I hadn't turned anywhere)
