Google Maps tests new pop-up ads that give you an unnecessary detour

Jesus, that is a gross way to inject advertising into turn-by-turn navigation.

Is there any way I can help contribute public transport information to OSM? It's the one thing that Google maps does that I can't replace.

Yes! wiki.openstreetmap.org/wiki/Public_transport though it is a bit complex to fully add routes, adding stops is super easy!
