That's the old way. The new way is to know cities, and street names, and neighborhoods, but the space between the cities is fly-over country or its a ribbon of asphalt flowing under your car, and maybe the names of rest stops along the way, one or two exits where you know a good place to stop for lunch or clean bathrooms.
Nothing in that is worth putting in a song I suppose. Our sense of place, of the value of a place, and of rootedness in a place, or the pain that comes from being uprooted from it, these used to be the subject of many a song.
Wikipeida has an informative history of the song here.
