I don't think anyone would have assumed that you can build such a system in a weekend. Half of your points assume that current transportation companies don't have any digital data about bus stops and reroutes. Anyway I haven't been in a bus that doesn't have such a system for at least for a few years (in western Europe and China).

> Half of your points assume that current transportation companies don't have any digital data about bus stops and reroutes. The question is what is more work: Using the existing data that is stored in some obscure format for which you first have to write an importer/converter or just recreating the data. Add the fact that the existing data might need some cleanup/additions (e.g. times on timetable are only stored with minute precision and you want second precision for more accuracy).
