A lot of people are genuinely stranded if their phone runs out of battery. How do they pull up a map, or call an Uber, or phone someone to pick them up?
I'm not sure the point you're trying to make. This was true before cell phones too. People didn't carry maps everywhere.
What's the difference between then and now?
Pay phones, basically? Physical maps being available in public places more readily?
The cellular phone network doesn’t require the internet to work.
