I'm surprised when I take a day trip with someone (e.g. hiking somewhere), and after using the GPS to get there, they also use it to get back. Personally, I can remember the last bit of the car journey and it's easily reversed. Then I just follow the "Copenhagen" signs until I'm near enough the city that I know my own way home. It's nicer than having a robot voice interrupt us every few minutes with "Take the left two lanes to continue on the motorway to Copenhagen".
