To sum up: the referendum to make the core of Berlin largely car free is proceeding past court challenges. If enacted, it would make Berlin the largest pedestrianized city area in the world by a long shot.

The downtown Wien area is gorgeous! They’ve got a good transit system to start with, so there’s no reason more of the city can’t become pedestrianized. I haven’t been there for a while, but I hope they’re making progress on turning the city into a better place for people.
A quick search turns up at least some efforts:
