Those census definitions are not good. I’m sure the place I went to high school is considered “city” by that definition, but the average HN poster would not recognize it as one, and there were lots of farm working trucks around.
It turns out that anecdotes don't constitute data. If the place you went to high school is considered "city" by the census definition, then I guarantee the majority of pickup trucks in the area were obnoxious luxury goods that never hauled a single thing to or from a farm.
