Why don't city buses form loops at the end of their outward run from central transport hubs? That way, with almost the same resource use, people could bus between the neighbourhoods at the end of the lines. Without coming all the way in to central interchanges, or the orbiter services, which usually connect the suburbs halfway between the centre and the end of each line.
I find it very frustrating that information about public transport routes and stops in Aotearoa aren't easily available in apps that use OSM and other open geographical data (eg OSMAnd+), or the transport apps I can find in F-Droid (eg Transportr).
Also that public transport planners in Aotearoa aren't collaborating on a single app and website, as well as (or instead of) their region-specific ones.
