When adding AI buses to the route, will it be possible for buses to join from off the map, i.e. from a road which is not belonging to the existing route? What would happen to a bus on a different route which turned left or right and headed off the map? Must it u-turn, or can it disappear and reappear elsewhere?
I am thinking of modelling one route, but having buses appear from other routes for part of the journey. I obviously only want to model the part of the map relevant to one route though.
