Seems like the JB area is full of primary roads. Too many I would think. As I am not entirely sure how to classify primary roads in town/cities, I usually reserve primary for a road that is really obvious (usually with terrible traffic jam during rush hour), while reserving much of anything else to secondary/tertiary. Even the osm wiki itself is kinda confusing. I just read the how to classify wiki, and it seems to indicate that there should be more primary roads than I previously thought. However, on the highway page, it seems that the classifications are more to the way I understand it since the first time I registered with OSM.
Oh well, as long as my routing app is not confused, I am okay with it.
