In my city, Linz in Austria, only a small part is pedestrian, and even then the main-line of the 4 (actually 2+2) tram lines is cutting right through it. I wish they'd extend the pedestrian area and add that second tram line overground rather than underground as the current political fantasies look like.

Anyways, from that article, if you have a change in a city's government, change is a lot more likely to happen. If only there were some time-limitations on mayor posts and the council.
