In situations where a highway has inner express lanes and an outer local roadway with all the exits and turns, I've used ramps to represent the outer roadway, as seen on State Rte 18 here. They seem to carry just enough of a penalty to prevent Waze from routing over the local segements unless it actually wants you to exit off them, but also won't route you away from those exits just because you need to traverse a whole bunch of "ramps" to get to it.
Of course, these local segments also don't have any driveways, be it residences or businesses. Personally, I think it would look a little silly for ramps to have addresses, and I'm not sure how that would even affect Waze's routing to those addresses.
Have we reached any kind of consensus on this?
