The reason for not being able to find a route, according to Dror, is interesting and now I need to get some help from the megamappers in terms of what you remember from the meetup about route pruning, road type preferences for route distance, etc. I haven't gotten that part in my recording, so I don't have notes about it yet.
Not much detail was given other than Primary Road wasn't one of the road types that were considered for the middle portion of long routes. Assuming we're typing all state highway/routes as Minor, then IMO Primary Road *should*
be considered and valued as a minor highway.
As far as pruning goes, I would imagine that at some point a route that's following along a Minor will prune before a route following along Major which will prune before a route following Freeway. What those thresholds are is probable a business secret and we won't know more than Minor < Major < Freeway.
Maybe we need to rethink how we type Major and Minor again and go more for what the road looks like, functions as, and capacity instead of going by US vs State numbered.
