Most cars around Romania are German made and used, most recently clocked or written off in that country. But the issue is driving culture and lack of policing I think. Romania had cameras and they were removed, the government claims, because they are against EU regulation. Naturally that's BS, and most laws are made in favor of law breakers not sure why.
Better roads & infrastructure (which lead to less car use and slower traffic), driver education, enforcing traffic laws do help though.
