Basically, if a non-major highway is the faster route with ZERO traffic on both that route or the major highway, it will STILL choose the major highway....because it's a major highway. It's only if the major highway is actually experiencing traffic that it doesn't use the major highway.

The entire reason we set at-grade connectors to have the same type as the roads they're connecting is because of penalties in changing type. Same with the instructions on what type to use for roundabouts depending on what roads they connect. If there wasn't a routing penalty for changing types, we wouldn't have to do that, would we?
The wiki is wrong if it says that. There are no penalties for changing type except for Private/PLot to anything else. Most of the type rules for connectors and roundabouts are mostly about aesthetics and not anything to do with how routing works, and most of them were written before anyone knew anything about the actual data model being used. Most of what we know now is only known because some editors developed ways to actually test the assumptions we thought were true or believed because someone heard from someone else who heard from yet another person who interpreted what was said in passing in an email and it's gone through 4-5 language translations.

Yes, Waze could "fix" the routing system by allowing long routes over minor highways. (Fat chance.) Or, we could fix the Waze map to provide Major Highways for long routes, which is what we're trying to do.

To minimize inefficient routing, it is important to be careful with the road type assigned to the Roundabout itself. Any routing penalty going from connected roads to the roundabout must be kept to a minimum, but it should not be too "attractive" where routing through it is encouraged when unnecessary.

In urban areas, "Highway" designations may be used to provide additional levels of granularity for road sizing. This depends on the state or city's categorization of the roads, using the terminology described in the sections below.
