Crucially, this distribution of border points is agnostic of routing speed profiles. It’s based only on whether a road is passable or not.

Only the travel time/cost values of the shortcuts between these points change based on the profile. This is a massive factor in keeping storage down – map data only increased by about 0.5% per profile to store this HH-Routing structure!
