In my personal experience, when I take a wrong turn, it's impossible to find my way back. I understand if you're describing the route from one large city to another, but if you need to get to a specific street in even a medium-sized city, it's impossible to remember every turn the first time around.
how old are you? How can you memorize a new route?
Because i am born in the TomTom era and i had google maps on my first phone ( not smartphone ) but it have it
