If it can make you feel better, I know a lot of Italian cities are going back to trams in dedicated lanes. This is on the back of the clear advantages enjoyed by those cities (Rome, Milan) who didn't actually rip out all tracks after the last war.

There is an element of busywork too: local officials are always elected by promising change, they have to be seen doing something. So on odd years they put in something, and in even years they take it out...
