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:

The city does score well on urban mobility:
