It’s interesting to see how people who grew up with smartphones think.
It’s entirely possible to get around without smartphones or paper maps. There are road signs, written directions, verbal directions. The main time I used to use a paper map was driving long distance trips in a foreign country.
I have one, but I haven't used it since I got a smart watch (I mostly used it to track my speed). I actually really dislike navigation apps, since they tend to take you on strange routes that maybe are slightly shorter? To be fair, I haven't owned a car in 15 years, so I rarely drive.
