> Sadly, they don't even attempt to have public transport schedules on the main maps, whereas Google has even added inter-city buses in some places
What Google is doing is to integrate public transport data (often in GTFS format). It is not mapped directly by Google, and unlikely that it would be doable in OSM (note that in many cities timetables change weekly, for example as result of construction).
There is some ongoing work to build similar things for OSM-using software, for example Organic Maps is at least trying: https://github.com/organicmaps/organicmaps/issues?q=is%3Aiss... (I bet that pull requests would be welcome, especially if discussed with people developing it)
