Hello.

Changing "highway=service" into "highway=busway" is a sensitive issue, since access permissions must be arranged differently.  In our city, bus lanes come under various forms, each having its specific set of exemptions or legal access.

This massive change of several roads should preferably have discussed with the local community beforehand.

It went under the radar because it was hidden under an innocuous changeset title, about the MapRoulette task for roundabouts.

I will try to fix those edits.
