If you have a large area that has nothing but regular streets and you need to navigate through it, the paths of least resistance (widest street, more than one lane, highest speed limits, fewest stop signs) are going to be your Primary Streets. That's where you want Waze to route the thru-traffic.
And as Sketch said, they might have a 30 MPH speed limit or even 25 (can't think of any like that ATM), where every other street is 20 MPH.
This exactly. The first and last thoroughfares I take every day are packed with houses with driveways.
Jason, Jackson Ave between St Charles and Tchoupitoulas (at least) is a good example of a street with a 25 mph speed limit that should absolutely be a Primary Street. All the strictly residential streets in New Orleans proper have 25 mph speed limits, too, but Jackson is the wider one with signaled intersections and no stop signs. A number of primary streets in New Orleans are like this, since the blanket law is that all undivided streets have a 25 mph speed limit.
There's no easy way to make a rule, but it should be fairly intuitive.
