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.

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.

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