I'm already seeing that flight to the suburbs happening here in Bucharest, yes. And, yes, the most recent census has confirmed that flight to the suburbs, that is for your "non-evidence rant" part of your comment.

Unfortunately, in my experience, to people who are concerned about “immigrant people with kids but not-interested in having a full Western-life experience (which necessitates having a car)”, this is what counts as a logical complaint.

It increases the cost of living in those areas, so what they are saying makes sense just because of that.
