You can even just go by street signs and general directions sometimes. I don't know if I have any paper maps any more. Plus, you know, reading maps while driving is probably as dangerous as texting.
The other day, I left home intending to go to a hospital near where I live. As I usually do, I plugged my phone into my car and tried to tell it to navigate there. But for some reason it hung while trying to contact Google to locate the address.
So I rebooted my phone, and rebooted my car, to no avail. Eventually I gave up, and based on the general knowledge that the hospital was to the south east, took one of the main roads through the city east, until I saw the first of several blue "H" signs directing me to the hospital.
My car has an electronic compass as well, if I didn't know which way was east/south.
