>>From what I see, Belgrade is neither more nor less congested than it was in the eighties or nineties.

NZ's problem is massive immigration, apparently now the highest per capita in the free world. Many/most of the newcomers prefer to settle in Auckland whose roads and infrastructure are severely strained. Once leafy suburbs are giving way to cheek-by-jowl living and ratepayers are presented with a bill for billions of $ investment to cater for all the newcomers, causing many locals to ask why we want Auckland to grow. Why not put up a "no vacancy" sign? It's as if tens of thousands of people declared they want to live in Beverly Hills and it's the responsibility for existing residents to contribute affordable housing and infrastructure so all-comers can cram in.
