in the world of historic preservation and historical archaeology cars and street furniture ( telephone poles, trash cans, benches mail boxes &C ) tend to be stuffed in the box of thing called "material culture" ... the way archaeologists decipher what civilizations were ( or are ) like is through their "stuff" ... plenty of archaeologists dig through trash pits, cellars, and junque left behind to "learn" about who left them behind.

whether we like it or not, cars are unfortunately part of modern culture ... and by including them as well as all the other things that clutter where we live ( garbage cans, dumpsters, street furniture, power lines, hideous architecture and other stuff i am too tired to suggest ) it gives us a clue as to who we may be. i don't mean to say that all this stuff "defines" us, but it can offer-up a piece to the puzzle
