I was in both Lisbon and Barcelona. In Barcelona, the narrow intersections were widened and the city "blocks have the same shape making the intersections feel not as crowded + also acts as a parking while also offering better sight to the drivers. Lisbon was close to Bucharest, way better I would say in terms of traffic, and I have driven around for a few days.
Barcelona ^
It's the first time I hear of white flight. We don't have this here, but we do have Rroma people, so I understand how that is a problem. Maybe that can be fixed too.
I don't know, I have many of my friends signing up in two new parties that are transparent, uncorrupt and made out of professionals (but total amateurs in politics). Some of my former friends are leading some local branches and some of my acquaintances are parliamentarians. The stress they are being put under by the actual government which knows nothing about anything except how to steal, is enormous. They are basically sacrificing themselves.
We will see, I still want to retire from IT and start my own BIO farm in ten or so years. We will see :)
