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

Even at unfamiliar places you can probably get by just knowning the general direction you want to go and glancing at street signs.

Highly depends on your location.
