I doubt if anybody under 30 can read a paper map. I held out until about four years ago when I got my first iPhone 4s. But you don’t have to get far out of urban areas for it to become useless.
I download GaiaGPS maps in advance so I don’t need a cellular data connection. But I still have paper maps,in the glove box.
Can you even still buy a good paper map? You certainly can’t as easily as you once could, I’m sure of that. I’ve still got a pile of legacy ones out in the garage.
