There are traits and things that are iconic and original in American culture, but it has more to do will population sprawl than anything else.
It's mostly because American streets, generally, aren't picturesque:
Consistency or a sense of harmony between architectural periods on your typical American street is basically non-existent.
They aren't neatly planned and subtle like you would see in japanese urban areas either, which both have elements that refer back to architectural staples of times past, and emphasis a pleasant neatness, without being neurotic.
High degrees of individualism make for a aesthetic salad. A lot of individual people who take pride in their home, but scoff at the idea of appealing to the pleasant effect of the total community being in visual harmony. It's collectivist, and generally seen as anti-American.
